Considering all that Yearn platform makes possible, it is no surprise to expect a big future for this token. YFI holders are incentivized by getting a share of the net income.
On the other hand, rising DeFi created lending pools and different opportunities to earn more crypto while holding on to your favorite crypto.
But not everyone is a seasoned trader, and the crypto market is full of risks and possibilities, so Yearn as a promising platform that will manage users' investment will be a well-known project in the future. So it would be wise to invest in this platform or even buy some YFI for yourself.
