It's true that the noble chain is often criticized for its high gas fees, but there are indeed many applications, and most of them have a bit of a gambling nature, which is quite addictive. I can hardly control myself; luckily, I managed to gather enough for a five-star with a cost of $281. The actual cost is probably an additional $30 just in fees... If you have some capital, you can participate. I suggest redeeming just once for the amount you plan to invest, otherwise, redeeming once incurs a fee of $1.5 plus gas fees of a few cents each time, which is truly unbearable. If you don't have capital, just take advantage of the free offers daily; it only consumes a little gas fee.
