Currently, we have only one bridge to ethereum, but it doesn’t mean that incognito <> ethereum communication is limited only to one bridge. Nothing can stop Renproject, wBTC or any other teams to maintain own bridges to the Incognito network. It might be “compliant (KYC)” or “anonymous (no KYC)”.
Soon we will see a market place of bridges & layer2 solutions for Bitcoin and Ethereum networks (an idea for builders), and ab user will be able to chose to use compliant or anonymous bridges.
I can’t clearly answer to you if you should worry or not, but I can recommend you to follow Unchained podcast, the host brings quite a lot of guests from different authorities. I do listen every episode. It will help you to see bigger picture in terms of what is going on there and what is a chance to be “tainted” if you are not involved in any illegal activity.
