make an 800% return over the next year, but if you believe in BTC, and you’re investing for the long term, the time to buy is right now!
What's the point of buying like $50 worth of Bitcoin and to hold that as long term investment? If you gain like 100%, which is a very decent return in percentages, you'll see that it only resulted in a $50 profit.
In other words, either invest a decent amount (and thus take a higher overall risk), or don't invest at all. It's nothing more than a waste of time if you look to invest with insignificant amounts. It may sound harsh, but it is what it is.
