If you invested on bitcoin and want to make profits you have to wait for years,it may happens earlier if you are lucky but you are not going to lose any money by investing on bitcoins when you hold it for too long period.
Investing in the Bitcoin for long term, like 10 years+, is kinda no-brainer thing for me. I believe that crypto will thrive in the future so buy now and keep it safe and just forget about it is sounds a good plan
