I should have done this with a smart contract on Ethereum instead. With a smart contract you could not say I would steal your money.
Yes could, If you're the person who code the smart contract.
If you could just channel this same amount energy and determination into something rather decent, you would be able to come up something that'd would be worthwhile and you can actually be proud of.
I'm rather the kind of person who try to take advantage of the market in compliance with the rules of libertarianism. In a libertarian society, "honest" Ponzi schemes (like mine) can exist, but you can't steal someone else's money.
Honest and ponzi scheme are contradictory words, in my candid opinion.
So it's no more risky to trade with me than with any other newbie.
I would make use of an escrow if needs be that I must trade with a newbie. However, If it can be avoided, I won't.
