If you are looking for reliable ones, try top coins.
altcoins investments is risky, i think everyone already know about that,
my simple strategy is by buy low and sell high, and hold a good altcoins such as ethereum, eos, ada and waves my friend
then, to find an atcoins with under $1 and will go to $10 for now is very hard my friend,,
Why are you investing in EOS, ADA, ETH if altcoins are risky? Also, being lower than $1 does not mean more earnings.
