every month are dozens of tokens/coins that die or appear...
I have noticed that the number of tokens/coins on the market has continued to increase since 2016 and has not decreased at all. This year the number of cryptocurrencies will definitely increase a little.
This is going to be the issue, as old ones die there will be 3x more created. It's going to be the most insane ponzi scheme you have ever seen because of the current economic times. People really need to be careful.
i hope people are now smarter than before. look at those projects holding their ico these days, very rare that you will encounter a project that raised their targets. most of them can't move forward because they failed to raise funds.
so that's a good sign over there. people dont trust anymore this type of fundraising. actually, the OP is already very generous about stating that about 10% will survive, i believe it is lower than that. look at the current list of coins or tokens. how many of them are existing for at least 2 years?
