Bitcoin is pretty good but it does have some fee, very low compared to other options. For every BTC transaction, there is a tiny fee for the sender.
When you convert the BTC into fiat, there are fees between 0.3% to 3% or more.
BTC is secure for you as a seller, but if you are also going to pay using BTC, make sure you receive your product before you transfer BTC because you cannot get it back no matter what you do.
Also remember that BTC, like stock market, is volatile and there are chances of loss as well.
