As of August 2018, there are over 1600 cryptocurrencies that exist, according to Wikipedia. I know that Wikipedia isn't the most reliable of sources because anyone can edit it whenever they want, but the point is the number of cryptocurrencies being introduced. Some of the new cryptocurrencies I've heard were DeepBrainChain, ByteCoin, IOST, and Elastos. There's also a new coin called Virie, which is apparently a cryptocurrency used to crowdfund and jumpstart the Virternity Project, a project that aims to digitized our minds, economy and the society. I believe that not all new coins aim to scam people, but do we really need more cryptocurrencies? Do we need new cryptocurrencies for every project that exists? Why can't there be one or five cryptocurrencies that all projects can use?

The success of digital wallets in the African continent was really great and based on what I've read on news articles about it, it really helped the economy and the businesses when it all started years ago.
With this in mind, will Africans be welcoming of bitcoin/altcoin as a real currency and not just a quick way to earn cash or invest? Like using it as real money / cash?

Is it necessary for token or coin to pay huge amount of bitcoin or ethuruem  for it to be listed on Exchange...
Why exchangers charge millions of dollars to get a token listed on their exchange?

You need law as things doesn't stay faithful and legal for the entire community, you leave crypto alone and unfortunate cases would definitely happen, there's gains and loses if something is freely exposed and some ppl would simply convert these processes in harmful activities that greatly benefit and harming the innocents, regulation is needed at a global level but that doesn't really match up with current positions from many authorities, there must a relationship for certain party for gains, so do regulation with all those collection of fees

For me it has been nearly everyday once for years now. 

I want to ask as a newcomer and still a beginner. What do you think about campaigns, but spreadsheets never change or don't update? Please share your experience and suggestions. Thank's.

There will be a fixed number if Bitcoins, and people, because of human error, will accidentally lose Bitcoins every now and then.

This must mean that Bitcoin will eventually seize to exist? Or at least shrink to minimal amounts, when it shrinks to a certain level, it will no longer be useful.

Is this correct?

I have one question that really bug me sometimes, Are ICOs going to end or new ideas and projects will emerge along with ICOs. Many of us actually rely on bounty to earn other than investing. As long as there is ICO I believe there will be bounty. It will be a sad day for us if ICOs are declared officially dead.

I started my cryptocurrency journey around July 2017. I bought some altcoins;  verge; dodge, Xrp Siacoin on Bittrex and left some on bitcoin. It was a roller coaster for me around November to December 2017, particularly with verge, my crypo investment of just about $120 grew to a little bit over $3,000. I never new on time until I opened my bittrex. It was wao!

I took out some money since I was in need about $1000. With the euphoria of bitcoin suppasing $20,000, so I watched until my investment shrinked from about $2000 to $1500, then $1000, I decided to take out some little more until I had about $800 left.

That amount have shrinked further to about $450. The worst came when I took a third of the amount to buy Mithril coin when the news came that it won a vote to be listed on binance,  and suddenly it was disqualified,  and the price have falling like packs of cards, more than 50% right now.

Its a question of if I had known, I would have withdrawn the $3000 the moment I saw it on my bittrex account. Who can tell the future?

But I am wiser now.

Does anyone have similar experience

I don't think KYC for airdrops offered is fair for those who joined. Some ICO with airdropping is not also fine to get KYC for tokens worth almost nothing or a burger meal is not really fine. I observed it in some ICOs with airdrops that even with giveaways like that so small needs KYC? Don't fall for it guys, not worth it.

I never understood why cryptotraders and exchanges support ICO's, my reasoning is this: An ICO gets funded, then they do what, they SELL the BTC they raised for fiat and push the price dive on BTC, thus taking all those BTC out of the trade environment, anyone thinking that an ICO would reinvest into the exchange is naive. This hurts everyone, even the exchanges. You might say "Well the exchanges get fee's on ico" well that is true, but they are losing all future potential fee's on those coins, if they had continued trade on the market.

So in Short - ICO's are killing Bitcoin and CryptoMarkets.
