I would create a more concentrated portfolio. Just imagine: If a position of 1 percent doubles in value, you only get a return of 1 percent of the overall portfolio. Just try to limit the number of coins to 20 at max.

I personally would sell TRX because of its great run YTD and its market cap.

Try to focus on smaller, add-ob tech coins like for example LRC.

I would have a look at XBY, UFR, CAPP and DBC.

PS: USDT is only a cash-proxy, invest that money!
