What don't you like about Bitcoin?

I think Bitcoin is great but I'm curious if there is anything that bugs you about it.

I'll go first.

When I first started to buy a while back it had a bad reputation. Anytime I brought up Bitcoin I would hear are you buying drugs or are you a criminal? It's reputation has improved since then.

Today I don't like the tax laws surrounding it and wish I could see that change. It's unfortunate we have to try to figure out cost basis and capital gains tax.

I'm curious if anyone else has different thoughts around this subject.
