The trend for the last bullrun appeared to be coins that focused on either privacy or scalability.
What do people think will be the trend for the next bullrun?
I don't even know that the trend for the last bull run is on privacy and scalability coin, Which bullrun do you mean? I am really interested to see your source and data.
The thing is I don't even see any bull run since the market falling in early 2017, all I see is red-bear market, and also some bulltraps occurs. You might need to redefine your "bull-run" term man.
