I have just participated in this market a few recent months and begin with some BTC. I am saving them in my cold wallet and I'm wondering how to bridge my BTC to another chains such as Ethereum, Polygon to get more profit from Defi. Please help me and give me some good ways (reasonable cost and safe) to do that. Thank all!
Let's be clear here. You wouldn't be "bridging" your BTC. You would be
trading your BTC for a token whose value may or may not retain the value of the BTC you traded.
