Having lost a great deal of money last month; i still belirvr some alternste blockchains will survivr. Actually, I believe there will be more than thousands.

Why? The solution space offered by blockchain is too wide for a single dedicated solution.

We have scams/shitcoins yes. I would put 90% of icos in scam category. But imagine the other 10%. They develop niche solutions that end up generating revenues... they have a reason to survive.

As bitcoin opened the way, and sets gold standard, we can go beyond that in time. It would be great not doing that with icos but just community efforts. However, ico brings cash together for a core developer team.

Any argument calling all altcoins scam/shit is wrong. Consensus creates the value.

I count more than 20 coins that have some sort of a future that I am very confident in. I also count about 20 that i am not sure, except they are not scams. Then i know of about 200 coins that are scams. Another 500+ i have no idea about... so, genrally speaking they are shit, correct. But not all.
