Yes it is. Bitcoin is the best cryptocurrency for now and it has very good potential and no other cryptocurrency can replace Bitcoin in at least next 10 years. Because of these things a lot of big company spent a lot of money to invest in Bitcoin cause they can earn money from it really quickly and JPMorgan Chase is a typical example. But Bitcoin is still not legalized worldwide beside it's banned in some countries so not everyone can take that opportunity 
You know, most times I think writers are very lucky, because there is always an opportunity for them everywhere lol. Though I dont mean to say theyre better than developers and programmers, but I know what Im saying, they can even be better than the two I mentioned. Everywhere I go online I usually see business opportunities for writers. Dont think of getting into writing just because of what I said lol, it might not be your profession.
