What is the best bitcoin business to create that will grow throughout 2017?
There's a saying: Be the best at what you do. Don't be the best at what other people do.
Don't go for all these fancy easy-money-making methods or businesses. My suggestion: accept BTC for your services and that's it.
Your suggestion to accept BTC for the services you've done is good. But I think it's better to invest so you could gain profit in a shorter span of time. Because if you're just accepting bitcoin as payment for your services done, then I think you'll gonna wait quite a longer time to achieve a high amount of BTC. If you target to reach a maximum amount of BTC then you must engage in a business that could give you an extra BTC income.
I am agree and that also make good bitcoin dissemination. Or maybe if you have good skill in computer, you can create service business that related with bitcoin, for example create exchange site.
