In my personal opinion only few coins like bitcoin, ethereum and few other coins will last that long, all other faster then bullet, partnership coins,and many other shitcoin will die. what you think?
While the coins at the very top of the market cap are the ones that have the greatest support from the community you will see that many are newcomers and have not existed for long, so out of the top 20 the ones I think are still going to be around by that time are Bitcoin, ETH, LTC, Monero, Dash and ETC, some of the coins currently in those positions could still be around but to me that is not a sure thing, only the 6 that I named have a very high chance of being alive at that time, and once you understand this you realize how volatile this market really is since I only selected 30% of the coins at the top, can you imagine the survival rate for the rest of the coins? It is probably below 5%.
