Welcome back to the forum, and learning too. Your decision to round up your formal education is a right decision; first thing first. Notably, your hiatus wasn't for a long time and I believe you will catch up with what has transpired here in your absence. Talking about what your friend has shown you as dividends from his investment in cryptocurrency, I hope you will tread carefully believing him hook, line and sinker.

Remember that it's not all that glitters that's gold. Most of these people who display the supposed luxury acquisitions as dividends of crypto earnings aren't truthful. I ain't saying people don't hit it big in cryptos. Of course people do but most of those who do make it big like to lie low.
