I used Changelly.com the other day for the first time and it was excellent. It has a better exchange rates than Shapeshift.io and I did not like the Shapeshift reviews
Maybe the days of exchanges are numbered now that instant exchange is available rather than buy/sell walls on exchanges
Do you think exchanges might become irrelavant in the coming years? The only advantage they seem to have is that investors can send their crypto to their addresses instead of having multiple wallets on their own desktop. With Changelly and Shapeshift growing they are causing problems for exchanges and provide greater anonymity too with no AML/KYC required
Exchange sites would continue to remain relevant in the scheme of things as it relates to crypto based on the following reasons that I can think of now:
1. There would always be need for market place where the price is determined by the forces of demand and supply, by the people in the market as against the other option you mentioned. On exchange sites, I can set a target then go to sleep, the next morning if the forces tends towards that direction, I make money while sleeping otherwise I wait. Also, it accommodates the services Changelly are doing because you can sell instantly on exchange sites as well. Just use the current market price and see your orders filled.
2. On the issue of KYCs while this is an advantage that Changelly and co has, it won't last long because whether we like it or not, regulation is coming and those promoting its ineffectiveness would be doing more harm to the market. Its as well better to start getting accustomed with it now. Another issue is volatility that Changelly must have whether the coin is being traded at the moment or not which is more risky for them
3. The fees is another killing thing I have used Shapeshifts, and I blame myself from the below market price they quote, down to the fees they charge for their own service and the payment of network fees, exchange sites are way better.
