That statement contradictive, to had changed your financial life you would of had to gain ie sell. Also you only truly make a profit/loss from an asset when you have sold.

I like POS coins and this one ive invested in early last year but if your a new investor only invest what you are willing to lose and that high ROI coins are not sustainable. As long there's a demand for that coin then your good but soon as that demand declines in time you will be in the shit. Its a risk and a gamble, all Im saying is be careful and dont have all your eggs in one basket.
