I read your story and it was really unfortunate. You could become a millionaire right now but you commit a mistake which is investing with a lack of knowledge that leads you to invest in Ponzi and losing half of your earnings while the other one is not saving your private keys. It is not bad to take a break from crypto since it was undeniably stressful sometimes but don't forget to save your private keys cause' it is the only way to access them. Just like you, I enter the crypto space in the year 2017 and I also used a blockchain wallet, I could be a millionaire right now as well but the mistake I did was to keep spending all the Bitcoin I got. I should have held it. Anyway, it is already done we should move on now and take it as a lesson. It is never too late to make an entry anyway so start up once again and never swayed by your past mistakes.
