Do you think it will be good idea to invest in all of them.
I don't click sites that I'm not very familiar.
But with your question if its a good idea to invest in 'all' of them.
For me it's going to be NO. Why would you invest in all of them? you can pick 2-3 and that would be fine or best focus with one privacy coin and invest to it. Have you heard it when McAfee said that privacy coins are the top tiers for upcoming years?
