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?
Honestly?Never let anyone to tell you what to buy because this involves your hard earned money and it would be harder in your part if the funds losses just because you entrusted this obligation from someone
Yes i have checking those coins from the thread like this but in totality its my decisions on what to purchase and in my experiences in this community it has been always the top 20 coins whos bringing income in my part,though sometimes i gamble in newly released altcoins but still the stablished crypto succeed
But try to check this thread for some optional chances of finding what you are looking
