I plan on doing both. I have some BTC, ETH & XRP stored in my hard wallet and have these coins as well as some other alts on Binance. I am going to day trade BTC/JPN at my local exchange as well as use BTC for bait at all those fishing holes on Binance!
I will of course continue to buy BTC & ETH to stash away on my hard wallet.
I'm still working on my strategy but this is where I'm at right now...just getting started, basically.
