According to me you should invest into Bitcoin and altcoins. Don't invest into ICOs
But ICOs also offer Altcoin! So that's technically wrong.
Right, invest in cheap coins or prices below $ 1 is certainly better and promising because it is easier to rise up to 10x, besides investing on new listed coins of course also good to be used as daily trading.
Not all of altcoins that have below $1 are profitable to invest, they probably just garbage and or they are keep dumping the coins without any support. That's pretty common on altcoin, so be aware of that.
