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.
Thanks for the heads up, I was surprised when I read about YFI. The major reason why the value increased that much was because of the supply of only 30,000 tokens and the tokens was earned by carrying out task in providing liquidity for other tokens of the project.
