Hi sorry for this question but I can’t wrap my head around this. I found out about bitcoin about a year ago but just started looking into it again. After watching videos and reading all day I finally came across this forum so maybe someone could point me in the right direction. I don’t understand how any of this really works. What I don’t get is when you put money in your account what or how do you do with it. Do you buy coins from other ppl that want to cash out.  That doesn’t make any sents to me. Idk I don’t get it. So far today all it got was IOTA was or is going to be as big as bitcoin, I set up an account at Coinbase,and one at Binance and I’m waiting for my account to be confirmed. When I understand this is there a minimum amount of money I have to put in. I don’t think there is but thought I’d ask. Thanks for taking the time to help me.
