There are lots of altcoins(well, ICOs) Can anyone suggest some altcoins to buy?
I searched some on ICO listing cites, but it seems a lot of them are paid to be rated high. Some coins have only 100+ members on Telegram...

I know that the price will go up and down but how to find some altcoins that is really doing something revolutionary and worth to invest?
if you are buy new project you can't predict about future.
but if you are buying on going project of complete project, you can find project are good.
because in this situation that project are survive.
like ETH, or LOKI, loki has come back from under 2k sat to 6k sat for now.
I think they will grow up more.
