This is one part I love about this post, realising your errors and learning vital lessons from it. Some risks are really worth it, but sometimes, instead of living in regrets, it is still fine to restrain yourself from taking certain actions if you are not sure of your actions. Although, this comes with consequences just like yours now whose consequence is the potential profits that have been lost so far. Although it is never too late to start all over again, but can never be compared to being an early starter. No regrets,  earning from Bitcoin hasn't ended yet.
