I use bitcoin to buy things all the time. Full stop. I've made a bunch of money from that investment too. Full stop. Having a currency that is not bound to a state can very possibly be a good thing. Full stop. Scams exist in many industries and in crypto it is rampant due to its lax regulations but that doesn't mean the industry is a scam by definition. Full stop.
I wonder if this is what telegrams read like.
