It's kinda ironic that we even need to discuss this, as the need for centralized exchanges is slowly fading away, day by day. The demand for DEX's is increasing, and fast. Sure I understand the sceptics out there, but let's face it. It's gonna happen slowly, but surely.
Most people are SICK and tired of KYC, exchange hacks, wallet maintenances at the worst possible times, and the list goes on and on.
Blocknet is leading the DEX development, and is a project I'm personally watching very closely.
https://blockdx.com/It makes me sick, that these centralized exchanges could at any time run away with everyones money, under the disguise of being "hacked".
Decentralised exchanges would clearly solve the problems of KYC and it would protect users from the excuses of "hacks" that you highlighted. I still think time is needed before these exchanges start shutting down and wide spread use of excellent decentralised exchanges are commonplace.
Do you have any views on what might be the first exchange to close down in 2020?
Why do you even want to know that? I stopped using centralized exchanges awhile ago actually. For large trades I do OTC with escrow, (know few reputable people, which is a must), for smaller trades I use DEX's, which is frankly the future, no doubt.
People who wants to protect their privacy is obviously using DEX's, and their adoption will grow slowly, but surely. Personally speculating on accumulating a few nodes in Blocknet, since I believe they will become extremely lucrative in terms of "profit" in a few years time.
