I know it's a bit anecdotal, but believe it or not folks, I still have friends approach me and tell me they're interested in getting a GPU to mine bitcoin. I tell them, you must be crazy. I then say, if you're actually interested in crypto currency, just open an account and BUY some. It's not that hard. So there are still so many people who are familiar with crypto currency, but have no idea what they're doing and will eventually come to speculate on it. For that reason alone, I would count on another ATH, but probably not for another year or two at least. Just my two bits, take it or leave it.
A new all time high record will be set eventually. The question is really whether it's going to be this year, next year, or perhaps 5 or 10 years in the future. That's the real problem that a lot of people are being faced right now.
Actually, if your friend is interested in crypto, right now would be a good time to get started.
The prices are super low for most coins and prices are essentially down 20-30% today. It's hard to see bitcoin continue to go down by 10-20% per day for the month, and I believe that buying now could prove to be a good decision to make.
You need to be patient when it comes to crypto. Nothing happens overnight, but when it happens, it happens fast.
