Very funny, did you loose BTW? Every "investment" is a gamble of sorts. And how can it be gambling and a ponzi scheme at the same time?

Also I did put investment in quotes. I don't consider it an investment like stocks of a well established company, but if you put money in a security and you can reasonably expect some return at some risk it is an investment.the main difference is that with gambling you play against "a house". A single entity that controls "the market". With crypto, you can take your security and sell it to anyone, or buy stuff with it.

And no, I haven't robbed anyone, I haven't forced anyone into it to buy at gunpoint. I haven't bought in by using secret knowledge. And If you think crypto is both a gamble and a ponzi I wonder what do you think about forex. If anything that looks a lot more like betting as 99% of forex "brokers" don't actually buy/sell for you, but you bet against them.

On Forex I lost £3500 when the UK brexit referendum went the other way than I predicted. Was I "robbed". No, I made a bad "investing" decision.

Have you never lost at a stock market either?
