There are lots of ways to know which coins are good, I suggest that you should read the white paper and roadmap follow the project on social media and pick most of the project from a unique source. By doing all this you will pick a reliable and unique project.

Etheruem is a top coin in crypto currency, after bitcoin the next alternative is etheruem that's why it plays a major role in the faith of other altcoins in crypto currency because most altcoins are built on the platform of etheruem which means any factor that affect etheruem will affect most of the altcoins. Etheruem decline in price that's why most altcoins drop massively in price, but I pray it will recover very soon than we thought so as other altcoins.

Am surprised at the price of etheruem and at the same time I am not surprised at the price of etheruem because we should have been expecting days like this, in normal business we have both profits and loss, both are major terms in business so the one we chose depends on our action towards the business, same applies to etheruem.

There are numerous advantages of altcoins, so it now depends on the area or aspects you are dealing with, the advantages altcoins have to me might differ from the advantages altcoins have to me. To me altcoins means a lot first they are just like raw materials ready to be explore, because they are very cheap to acquire and rises quickly, moreover the profits in altcoins multiple in folds.

Honestly speaking you are not only the most worried now, because most people are feeling what you are feeling, most people are willing to ask the same question you asked, now that you have asked the question that is on the mind of most of us, I will follow this thread to know more about the solution to it, because I am sure that veteran in the house will enlighten us about this and even break it down for us to our own understanding.

It only depends on the type of project you are participating in, in some projects bounty hunters become ICO investors while in some projects reverse is the case, but from my own point of view I think bounty hunters should become ICO investors because bounty hunters are the ones that create awareness about the project which allows more investors to know more about the project and invest in it.

More and more airdrops is a lie and it is also true, but it only depends on the type of airdrops you are participating in because there are lots of airdrops outside there, some airdrops worth the effort,  time, resources and dedication you invested in airdrops, while some airdrops does not worth the stress, time and effort because they would only give you peanut as stakes, that's why I said it only depends on the type of airdrops you are participating in.

KYC for airdrops, I strongly suggest or recommend that KYC should be removed from airdrops campaign, though KYC is a great tool in business and have been contributing positively in business am sure that is why it is introduced to crypto currency, though in crypto currency it has been a major hit because it helps reduce scammers and allows project to know who are investing in the project, but introducing it to airdrops is a no go areas for me.

All coins are dropping because of the current market situation of crypto currency, Bitcoin set up and determined the market
Moreover etheruem is also down because bitcoin is down. Etheruem is widely used,  most altcoins uses its,  because most altcoins are built on the same platform of etheruem. Only if dumpers can hold their for a certain period which will give it more value.

I disagree with this, From my own perspective I think bitcoin is the king of all coins and it will remain the king for a long period of time while etheruem is the king of all altcoins that's most altcoins uses its platform, it is very cheap and affordable to acquire than bitcoin. Etheruem is just like a alternative to bitcoin, it cannot replace it either now or in the near future.

There are lots lots of tactics you can execute when market keeps falling but I would rather let you know the easiest and convenient one to do, immediately there is decline in market price just like this current situation, first keep your tokens don't dump, secondly buy from those that panic and dump, After buying from them hold again till the market recover back and rise again. This simple trick will double your money.

Sincerely speaking you are right about this it is hard to detect scam bounty campaign because most of this scam project clone it to a certain stage that you won't easily detect maybe it is scam or a genuine project but I can suggest that you should pick your bounty campaign from a good forum like bitcointalk and from well known bounty managers,by doing this you will cut most of the scam projects.

Naming the new king is not as easy as it looks, choosing a new king is not a day job because there are some criteria you have to choose or check before choosing or naming your new king, but for me bitcoin remains the king of all coins and it will remain the king for a long period of time because no other coins is ready to meet up with the standards bitcoin had already set down.

Honestly I still believe in bounties and crypto currency if not you won't see me here reading a lots of post, and commenting where necessary because I believe in crypto currency 100%  I am still dedicated to crypto, my commitment towards crypto currency is still intact though there are up and down in crypto market, but I believe the market will recover soon and rise again.

There are many ways or medium to check whether an altcoins is geniue or fake, mere looking at the name of the altcoins you can't decide maybe its a good project or not but you can take your time to research about the project, read the white paper, read the roadmap, follow the progress of the project, know the team involved in the project.

Waves vs etheruem, I don't really see much debate about this two coins the two coins are top coins in crypto currency they are multi functional coins but both coin use different platforms, from my own point of view I think etheruem is preferable to waves, because most project uses the platform of etheruem to operate. I can only see waves as an alternative to etheruem, not a rival.

There are many speculation because of the current market situation of crypto currency, there are lots of suggestion some say it will collapse, some say it will rise again, but am optimistic I believe in crypto currency I still believe in the market, I believe that very soon the market will recover back to its normal price and by that time there would be stability in price because the fluctuation won't be high anymore.

Why can't I wait, honestly waiting is the best option now because the market is down and some people are scared maybe all these coins will collapse totally they keep dumping their coins which makes the supply more than the demand as a result of this the value of the market will drop which makes it to lose its value. Just excersie patience and hold I am sure you will excited whenever the market recover back to its normal price.

Etheruem is the king of coins, I agree and at the same time I disagree. I agree in the sense that etheruem is the king of all altcoins, it is very popular and affordable to acquire, most altcoins uses its platform to operate because its simple and secure to use, it can be easily traded but all the characteristics above doesn't make it superior than bitcoin, it just serves as an alternative to bitcoin, bitcoin remains the king of all coins. All other coins including etheruem are struggling to meet up with the standards bitcoin have created.

Why so many bounty campaigns are extended is very simple but from my own point of view I can attach it to some factors which I list below.
unable to meet their softcap: some bounty campaign manager will extend their bounty campaign so as to create more awareness about the project in order to attract more investors to invest in the project so that they can meet the softcap. While some projects will meet the softcap but will be unable to get listed on the exchange due to one reason or the other. So by extending the bounty campaign they tend to meet up their setup goals.
