Any suggestions?
The basic way would be, to buy more bitcoin and HODL it for a long oeruod of time and just consider it as your personal asset than a form of payment. Bitcoin ia ever growing and its value will surely pump. On the other hand, if you feel like doing something you could try mining ir trading, this require you initial fund and work. But as you do it so well, you might gain greater profit.
As an add on, Initial Coin offering would be a choice for you to invest. There were legit project out there and you just have to take a look on the white papwr to see its future to offer. I've been particioating in ICOs and Ill be honest that its so risky and demand long period of time, but actually give greater profit than any other bitcoin activity.
