If Bitcoin price increases suddenly.
Does this change encourage buyers to consider investing in Crypto solutions like ICO platform or Exchange Software Development for their Business?
Bitcoin prices always increase from time to time but ICO is getting worse, and there are a lot of new exchanges coming from ICO and majority of them are failed project, so no I don't think so, ICO and exchange platform are not attractive anymore to investors.
Bitcoin price will continuously attract investors interest from the coin itself but with ICO and exchange product it will depends from how the investors will embrace the product, but it won't change anything as bitcoin will cycle and follow the path of success, there's no solid evidence that any investors will relied with bitcoin movement to invest with new projects it should be learned and study carefully.
