Hello, my friend. Long time no see.

This is a good question.

While some wait for the fantasy of seeing the BTC rise to 100K or more, others are enriched by trading, taking advantage of its ups and downs. It seems that this is the most attractive feature of crypto currencies today, besides the casino games. I guess that bull run is what keeps the interest in crypto currencies alive. I didn't see the video, they look like the kind of people who claim to have gotten rich by investing in crypto currency and convince you to join in with a plan they have to make you "rich" too. Obviously you have to pay them a fee.

I guess there are already many companies and exchange companies that have invested in BTC, so I think they know it is safe to keep investing in crypto currencies. Besides, many sectors have already accepted the use of them. So I think it is always good to invest or have a part of your money in crypto, even if it is to save as I have done.

Glad to hear from you ^_^
