Invest in coins right now unless you have buy some graphic cards at MSRP, if not it's better to invest in BTC and ETH or other strong altcoins like BNB and sit back to watch your coins grow, right now it's a 100% bad idea to build mining rigs because GPUs are too costly
I wouldnt suggest to newbie buy or sell coins because he can end up loosing money all.Unless understand in trading i will say ok.
