Beware, i sent Dave my ethereum pre-sale wallet months ago and he never replied. Now i can't even check the balance because he probably stole my ethereum. Biggest mistake I've made in my life.
Cool story newbie. Dave have on countless occasions spent his hard earned time to recover much bigger wallets than you probably have and gotten much less than he deserves.
Who do you think you are to open a scam accusation against him?
If what you mention is indeed true, kindly open an scamaccusation thread in the relevant sub forum with your evidence. Cheers!
