My struggle with crypto tax calculator sites

As many of you will know there are several websites that offer services to calculate your taxable income from crypto currencies (e.g. koinly).

I am in crypto for 6 years now and just recently tried such a tax calculator and am indeed very satisfied with the result. Things I tracked in an excel file for years manually and effortfully can be done within minutes.

The concern I have: If there is a security breach and customer data gets leaked, hackers could link all wallets to my e-mail address, couldn't he?

So basically you are giving up the pseudonymity of crypto and possibly make it traceable to you as a person.

Would be happy to hear your opinions on this!
