But selling into what? When ETH dips, so does BTC and LTC and vice versa. Unless you are selling for cash/fiat? I guess this is where I find trouble, the whole market seems to follow one another, aside from the few shitcoins that get pumped randomly.
More power to day traders that make a profit, I just don't see where to go when the inevitable dip comes.
Perhaps USDT?
It's true that hodling is the easiest and most effective. Trading has its time frames as market activity and would make a lot of sense to have it gamified instead of just being a gamble, which is why stuff like numerai and santiment are interesting projects. I guess keeping some coins in decent-volume exchanges is just all some fomo going on :)
