I don't think now is the right time to start hunting for altcoins and start investing in them. If Bitcoin was to fall further below $20,000 then as altcoins will fall further. The alternative market is currently very unstable for altcoins as that of Bitcoin is currently taking a beating. You can pick some altcoins that are currently oversold and keep an eye on them waiting for the opportunity to grab them at more discount when Bitcoin fallen, no need to rush.

Bitcoin can't withhold that support level at $29,000 it's holding for long, soon it'll fall and that corrections will take it below $20,000 but an immediately bounce back will follow since at that price is Bitcoin support many traders are targeting to get some Bitcoin at.
