I have done it in 2015 then reached my business goals and invested 5k in Krypto, hope was to get my 100k in krypto which I lost in 2013 back, back with the plan, then businesses were closed, so my income cashflow gone to zero but the krypto gone to 1 $ Million and fallen back to 190K by this minute so I am not a millionaire now in $ only in mindset so I have not cashed out in fiat yet because I think since years that crypto is king and only mass adoption is not there yet.
Thank you @incomeblogger for sharing with us your experience with crypto.
