You know what's the worst thing an investor can do in his investing journey? Not investing at all when people are scared of investing into it.

You're a newbie at that time and it's quite normal that newbies have some doubts into their minds when they see something for the first time especially when there's money involved. It's normal that they will be afraid at first because their hard-earned money is at stake.

As for you, no need to be furious about. There are some investors out there who also experienced the same as you are. They also have doubts in their mind when they first heard about Bitcoin. Anyway, you can't bring back the past anymore. The only thing you can do is to just move on, move forward and continue accumulating. After all, you started it already. Just continue what you are doing and for those newbies out there, OP said to invest now, but that doesn't mean that you will invest without any proper knowledge at all. Do a research first before investing.
