What is the best bitcoin business to create that will grow throughout 2017?
IMO the one and only bitcoin business that will grow not only throughout 2017 but beyond is Bitcoin Exchange.If you have good set up and earned the trust of users,your business will always prosper.If bitcoin market is down,other cryptos will keep your business running.That is why exchange are best
Having a successful exchange is obviously very good but you can do the same with a casino, in fact I have seen that a number of casinos accept other cryptos as well, so that is a strategy you can apply with other businesses as well.
