First we see bitcoin making gains and when bitcoin falls in accumulation we see Ethereum gaining when ethereum starts accumulating... We see Large caps crypto gaining momentum and breaking when these start accumulating we see the smaller cap making gains..
A lot of coins out there trading against USDT don't have the low risk opportunities as these pairs have against BTC..
This can be a switch in strategy I know.. but if you are a believer in bitcoin. I would ask myself (if I was you). Do I want to make more bitcoin in the future or USDT?
