$CFX Actually, I suggest everyone buy a little cfx and stake it in POS. Sell the interest regularly every half month, or buy low and sell high (when the interest price is clearly higher than the average monthly APY value of the staked cfx, that's when the price is too high... This is a simple summary, and I hope some expert can research a value model for everyone's reference). It is only recommended to hold long-term if the APY of cfx's POW + POS is below 5%.
