Yes, that is correct as of now.
Until and unless someone else discovers a way to produce more hashrate in other algorithms.
Vega still performs pretty good but not worth the price as difficulty has caught up.
For the price I'm not seeing it to just have an advantage in 1 algo. Is it true that not many exchanges want to host cryptonight coins? Also have people ever made some kind of modifier drivers that gives higher hash rate,?
What is the best pound for pound card out today?
The advantage of Vega is long gone. If you would have purchased it when the method for high hashrate in the cryptonitght algorithm for Vega just released. The break-even was in a month or two. Now, its more like six months with the price and difficulty.
I don't know if exchanges are deliberately not listing cryptonight coins.
No, there is no modified drivers but BIOS mod, power tables and such which provides high hashrates.
If you can find RX 5XX series for a good price or GTX 1060 and GTX 1070. They seem the best ATM.
