Just an advice from me to you, do not invest in new YFI copycats popping up on daily basis due to the huge success of YFI. We all saw the surge with YFI price currently above 22,000$ which surpasses BTC price right now. This is causing a lot of FOMO and scammers are taking advantage to launch their own scam coins (YFI copycats). Examples are YFIE, YFIS which launched even without website or team information, yet people still FOMO to buy. Be careful please, just a peaceful advise.
With the skyrocketing price of YFI, many projects are copied and I agree we need to be careful. If you want to invest in YFI, it's better not to buy copycats because they are prone to pump and dumps.
