Well, I still don't know anything about what really drives bitcoin or crypto in general, but I do know I personally love the stupid digital currency! I haven't bought anything with it or used it in any way; but, dang! Over the last couple of years, I slowly bult my bitcoin holding, a 10th of a coin, here, another quarter coin there. At the time I was buying, it's value was ranging from 3k-7k and I would just look for it to dip and buy a little. I ended up with a little over 6 bitcoin total (including 3 I bought at ~$15 and never sold) and then I thought, what the hell am I doing gambling so much on such a volatile thing? So I just held on to it. Well, I wish I had had the guts to gamble and buy more. This morning, I sold 4 bitcoin at right over $47000 per. I am very tempted to sell my last two coins, but what the hell? At this point, I can hold a little more.
I still have 300 Electroneum coins that have actually declined significantly in value since I bought them like in 2017 or 2018 at about .01 a coin. I also have a bunch of free coins that coinbase gave me just for watching videos to learn about them. I got like $6 worth of Maker coins (and traded a bunch of other free coins for Maker) in December when it was valued at around $500; it's now worth about $2500. I got $10 worth of Stellar Lumens (XLM) in November when it was worth .05; it's now worth .46. At my son's urging, I bought some Doge on a lark (5000 coins) when it was worth less than a penny; it's now worth .07.
So yeah . . . don't ask me what the hell any of those coins are actually good for or where I can use them. Instead, ask me how awesome my new Tesla is . . .
