Hello experts
I have invested 3000 USDT at these four coins.
$DOT
cost: 5.7$ Capital: 1000$
$ARB
cost: 0.97$ Capital: 1000$
$TIA
cost: 6.5$ Capital: 750$
$FIL
cost: 6.13 Capital: 250$

Only profit generated by DOT but it covered by the others losses. Should I hold or sell at loss?

I bought $DOT at 5.68$ rate. For which price should I sell it? Can DOT break it's previous high?
