what happens in my opinion for market now that the market is correcting prices that occur in 2017, because in 2017 prices have risen very high and this year the market price has dropped due to price adjustments and now is the actual price, but I'm sure the market price will definitely increase again in the next 2-3 years.

buy coins whose prices go down but before the market fall the coin prices are very high and the coins we buy must be able to survive and volume market very high, such as ETH, BTC, IOTA, Ripple and Eidoo then what we do is just hold until the price rises high.

if you are looking for big profits with a big risk, but for the short term, Altcoin is better than Bitcoin but if you want for long-term investment, Bitcoin is better than altcoin because Bitcoin has less risk than the Altcoin for the long term, because Bitcoin is stronger than altcoin and bitcoin it will definitely survive and increase its price in the future (long term).

what I want from ICO is of course profit, because I invest in ICO to get profit, so I will definitely choose ICO correctly and there are several factors before I invest in ICO, that is :
1. ICO has reached softcap.
2. the bonus amount given is at least 20%.
3. already have a product or MVP.

the one responsible is yourself, because investing in ICO must take the risk to get a scam, so we must choose the right ICO before we invest in the ICO, because there are no legal rules about investing at the ICO, so in my opinion the law will not be able to help us for return our money.

which determines good or bad tokens not the amount in circulation supply of tokens, but from platforms and teams, if the platform is good and the team always supports investors, I am sure the tokens will be good and prices will increase, so determining the good or bad tokens is the token platform and team not the amount in circulation supply of tokens.

If you want to invest in Crypto for the long term, then I suggest you to invest in ETH, EOS and XLM because I believe this coin price will increase very high in the future so that your time is not wasted because it has waited for a long time.

in my opinion, the price of DOGE will never increase very high, because the price of DOGE will stabilize only up and down in that number and investors also use DOGE only to make transactions (because the fees from DOGE are very cheap compared to other coins).

of course you are right, because if you don't take your time to read the whitepaper from the project then you will never know about the project, and cannot predict when the project will increase or decrease and whether the project can be for long term or short term investments.

Bitcoin is an important pillar in cryptocurrency, besides that Bitcoin is also the king and top 1 cryptocurrency, so in my opinion if bitcoin is banned then no one can replace it, even Ethereum ranked 2 in coinmarketcap will not be able to replace Bitcoin, so if Bitcoin banned then there will be no more crypto (in my opinion).

No!!! because in my opinion the next bitcoin is Etheruem and not Ripple, even though Ripple once defeated Etheruem but Ethereum easily defeated Ripple again (because it's difficult for Ripple to defeat Ethereum forever), therefore what I think is worthy of being next Bitcoin is Ethereum and not Ripple.

advice for you from me, but this is my personal opinion :
1. Don't buy altcoins with small volumes, because to sell them later in the future is very difficult.
2. invest in the top 100 altcoins (the biggest top 300), because it's safer and the price will definitely increase in the future.
3. don't sell your altcoin when the price goes down (panic sell) because it will make you regret when the price goes up, so you better hold it (because I'm sure the price will increase).

The best Ethereum wallet in my opinion is Myetherwallet.com and MetaMask, because the wallet is very good to use and certainly very easy, so I really like to use both of these wallets as a place to store my Ethereum and altcoin ERC20, because Myetherwallet.com and MetaMask support for wallet altcoin ERC20 too.

if I personally, there are several criteria for me to say that the ICO is shitty, that is :
1. the ICO date is not in accordance with what was written, because the ICO gets a lot of investors so that he submits and increases ICO time.
2. the bonus given by ICO does not make sense, which is more than 60%, some even have bonuses that can reach 100% - 200%.
3. never update the latest information, such as the number of tokens that have been sold during the ICO and the progress of the project.

I agree, because many ICOs use Ethereum as payment and of course that makes Ethereum is ICO king and that i believe Ethereum prices will increase very high because many people use Ethereum, so in the future Etheruem prices will definitely increase and Etheruem volume will also increase.

my advice is better you buy Altcoin Stellar (XLM) because this altcoin will last forever and for sure the price will increase very high and give you a huge profit in the future, so I'm sure you won't regret if you invest in Altcoin Stellar (XLM).

My favorite ICO for now is about Blockchain, security and infrastructure because in my opinion this type of ICO will be able to survive in the future and be used a lot so the price will definitely increase very high.

I will give you the name or list of altcoins that are worth to HODL, that is :
1. Ethereum
2. Ripple
3. Stellar
4. NEO
5. ADA
6. DOGE
7. TRX
8. ETC
9. NXT
10. UTNP

I don't think there is the next bitcoin, because no one can replace Bitcoin at any time, but even though one day there can be the next Bitcoin I believe it is not Litecoin but Ethereum, because only Ethereum is worthy to replace Bitcoin.

I think this is a normal thing, because from last month the market price always increased  and dropped as it did today, so I am not worried about what happened today because as usual the market price will increase soon.
