For possible 3X 5X in long term it will be wise to check top ranked coins instead of coins which includes high risk.
ETH, LTC, BNB and EOS are strong coins last proved them selfs during last 4-5 months overall market dropped.
While many coins found new all time low in these period drop of top ranked coins were mostly parallel with BTC.
I believe that only strong coins will survive.
low liquidity coins are easier to get 3-5x than top ranked coins, whales just need small money to make 3-5x happen
last dropped market affect to most of altcoin, no matter low or high liquidity coins
but we have to know that investing in low liquidity coins is very risky, same as proverb
high risk high return
