Hi im trading altcoins on exchanges for years now and i was always withdrawing like 60-70 percent of my profit
and buy bitcoin for the rest (30-40 percent) but since btc price is highly increased you think i should just keep
doing the same or i should buy USDT instead with that 30-40 percent meant for bitcoin and store it in a safe wallet
like trezor till btc price drop or till we see a new bear market then buy btc with that saved USDT

btc is now quite high,
if I were you, maybe I would take a safe or conservative step by buying btc when the price corrects
so for the time being maybe I will put it in usdt or in other crypto then do small trades there, when btc has reached the correction price then I will start trading in bitcoin again
