If this is your first time on this chart, this was a forecast from Feb 2017 back when Bitcoin was in the $800's. The blue and yellow lines have held up amazingly well over the course of the year.
As long as the later two of the above don't **'* up the confidence of the market players too badly when it comes crashing down I believe the true digital scarcity of bitcoin is what makes it fundamentally valuable.
Like gold, but without the physical issues of holding.
Just keep your private keys to yourself, don't put your trust in an exchange. Unless you are really prone to margin trading, which is a recipee for ulcers when in bitcoin.
