We all know at the moment bitcoin is not a legal currency in the world and it has many political barriers but still it continues to grow for years among general public and the business world so my concern is how far it can go or how far governments and other significant organizations will allow bitcoin to continue its journey without being accepted as a legit currency?
You can State what do you think because your bitcoin investment depends on that
If there is no active involvement of government in such matters, either positive or negative, bitcoin and other cryptocurrencies will likely reach a level of saturation after a while where it will be staying for many years to come. It will take its niche as a specific means of payment and investment or speculation vehicle, mostly in the Internet, but it won't be able to undermine fiat as an established currency, the one which is actively used for payment everywhere. There will be a certain sphere of application, a crypto economy of sorts, with borders, but it will be limited.
I think this is the most realistic scenario.
