I don't think all of them will go down, but I think the ones that are most likekly to replace bitcoin will have the most support. IE are the easiest to be able to change fiat into cryptocurrency and back to fiat. Have the most venues where you can actually spend the money. ETC.
With that said I have no idea, but DASH maybe a good one to check out.
Topic: Other main coins with huge community? (Read 386 times)
What other coins are there to gain huge value if bitcoin one day fails? It doesn't seem like btc is going anywhere but just in case , if bitcoin goes down , is there any that would go up? Or would all of them go down with bitcoin?
