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.
And just as expected, this is the usual style of scammers and cyber criminals, they copy the success of other projects and even have a close name to the original so that those unsuspecting victims wouldn't notice it and instead think that it is the same project or a new one and it will also be a success. As for the original, you have to be very careful as well, it has grown so much that there is a big bubble already. FOMO is real and so when this burst, it is going to have a negative impact to altcoin market.
