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.
Not everyone have these skills and so many people pay a lot for a good writing. The only difference between writers and programmers is because this is a digital age and programmers are highly needed for their skill which is why they get paid a lot for it, which is still not an easy job too, otherwise everyone would be a programmer by now.
Well there are writers that are born with this capacity. While others need to learn the tricks on how to become a good one. But yes, its not a easy skills and it takes a lot of practice to perfect this craft. I'm programmer and its not that easy too, plus technology evolves, so to keep up with the latest trend, you also need to update your skills. Although right now, programmer is very easy as compare to like 20-30 years ago. Right now its almost easy to create apps from scratch, unlike before.
So I believe no matter the kind of job youre looking for even signature campaign, programming, writing and the rest of them, you can find them here.
