I'm not taking any chances this time, I'm fully into crypto and bagging more pieces of bitcoin to my best effort. Already done some mistakes in the past which is a total regret, but today I'm a little bit happy to start. The best time is to start now, nothing abstract because there's no time on our side. Bitcoin have made both dump and pump movements over the years, some of us missed out while some made good profits during these times. It's very simple to purchase bitcoin, crypto exchanges have that easily possible, the space is advancing to the next stage and we should grow with it and it's adaptation.
I think you should not regret it if you learned something form it. I mean obviously you know what you are doing and that's the important case here, if you learned from your past mistakes then you are doing fine and shouldn't be worried about it.
I personally did make some mistakes back in the day but I do not regret them, I made those mistakes to learn what I should have done now, thanks to that I am going to be richer in the future as well. I am not saying I will be richer in a day or so, I am just saying that I made mistakes but I can be richer in the end "one day", maybe I will make even more mistakes and learn from them as well, but this is a way where you can actually become a better investor and get richer gradually.
