Runes are so popular that I would feel sorry for BTC halving if I don't try them, so I withdrew 1000u to buy runes without saying a word, and received 700u. I bought 500u, wanted to sell them at a loss, but found that the handling fee was not enough, so I recharged 500u again, and received 300u. I sold them all and sold 100u. In total, I recharged 1500u, sold 100u, and transferred it to the exchange. I still have 3u left. Finally, I did not miss this wave of market. I can proudly say that I don't owe BTC anymore.
