I don't like this token. It looks fantastic that YFI ATH was higher than BTC (82K) with total amount of tokens in circulating 36 638 YFI coins and capitalization a little bit more than 1 billion. Just compare with BTC: 18,905,200.00 BTC tokens in circulating and market cap of $979,968,312,106 USD. I think that YFI was artificially pumped by its developers or something that is why price suddenly jumped so high but then felt down again. If it is so, than those men can again pump  and dump YFI at any time.
