Yes, I think it is possible, in the long run, to figure out who's behind a wallet, assuming that the Bitcoin use is frequent and convenient (meaning no-super-high-inconvenient-counter-measures are used, but a regular use of currency)

In that case, my concern is that I think it will be possible to determine ALL the transactions of that wallet. Making it even less anonymous than regular currencies.

I could be missing something, but if confirmed, that could be a problem for using Bitcoin as a regular currency

There are various laundering schemes, and there's nothing stopping you using new wallets constantly.

But yes, in effect, every transaction is traceable and public, AFAICT.

Yes, I understand that there are things that you can do. But, as those are in the way of convenience, we can assume that not everyone will take the extra effort to create constantly new wallets, etc.

So, in case someone can trace you to a wallet, that someone can know all your transactions (of course, only the transactions for that wallet), which is a huge potential privacy risk.
