No it should not. That was only an issue with Iota because of the confirmation system that was used.

do you like my sig for WAVES? 

NO ONE should EVER under any circumstances deposit to anyone except their own wallet from an exchange. If you don't know this, you deserve to lose your coins. Period. If you don't own the key, you can't prove it's yours. Do you buy groceries by leaving $100 on the floor of a supermarket, and 45 min later just claiming they were yours?

Why do you need to PROVE its yours if you are depositing to a unique deposit address give to you by Waves?

Amount of invested BTC on the first day has already exceeded my expectations.

Well WAVES deposits for the first day are much more than I expected - so congrats to the WAVES team.

So one should have at least 50 posts before being able to participate in the signature action.
That means that I have to be around here more often. Trying to help others and also maybe making a bit of fun.  

You need to have activity of 60 to become member.

This is good for privacy in general, but it is also true that it is harder to audit. Did you guys generate the unique addresses via an HD wallet? Would you be willing to provide the list of all addresses for independent verification?
