Bitcoin as an impenetrable fortress of validation (Understanding the Bitcoin network without math)
I’m very new to Crypto and was wondering if anyone could help me.
Recently, I bought $70 worth of btc on **Coinmama** using my **prepaid visa card** for the 1st time.
The order **was completed** but strangely enough, **no amount was deduced from my card’s balance**.
On my wallet (Using Electrum) , it says that I have **an unconfirmed balance of xamount btc**.
Is this normally supposed to happen or am I supposed to confirm the payment in some way?
Thank you for your help
I have this “friend” who I lent money to like a year ago. Recently he made a bunch of money from poker and I guess bitcoin. Anyway instead of paying me back he put all his money in to bitcoin shorting saying go big or go home. He did this like 3 weeks ago. What does this mean and is it a good idea. He’s a dumbass who likes to bet a lot so it’s sounds like he’s betting with my money.
