Sending 80 to a wallet, then deleting the wallet and anything to do with it.
Not backing up a wallet seed, with 5000 worth of coins and the USB it was on sh1t itself.
Not investing at 30 a coin because "they are too expensive and will fall again soon"
Probably buying 20k worth the other day, to see them at 330 today!
I am sure there will be more fcuk ups to come.
Consider yourself unlucky. I hope that you learnt your mistake and will try to avoid it.
Buying Steam Wallet code in suspicious and disreputable website, I've never receive the code til now.
It's worth $25 Bitcoin
I'd recommend you Key4co.in, they are very reputed company in Bitcointalk. I bought two games from them and receive my code on the same day.
