Well, it's not switching until "the upcoming months", which is usually a euphemism for a couple years. But I'll cross that bridge when we get there. You've got some contenders there, but we'll have to see what coins become prominent enough to be listed on the major exchanges and what algorithms are supported by the big dogs of mining software.
A few months is an eternity in crypto space... who knows what will float to the top by then, if nothing looks profitable enough to make it worthwhile I'll shut my rigs down again and just fire them up when a decent spec comes along.
It makes most sense to might whatever is most profitable and then exchange what you have mined for your cryptocurrency of choice. There are various website calculators that help you determine profitability.
I've moved over a lot of my stuff to ravencoin for now. Profitability is now about equal to ETH for most cards and tbh I think RVN has a bright future. Bought a bunch of ryzen CPUs as well for Monero mining right before the price jump so I'm hoping that turns out well.
