Bitcoin is definitely still the best choice. It doesn't make sense to accept a coin that almost nobody owns in your business. Besides that, the high fees on Bitcoin are a temporary issue, this year some breakthrough will happen.

There is not much needed to make bitcoin payments cheap and fast again, because I think the last year the network is spammed by big block advocates to force their will trough the community. Exactly when Segwitx2 was signed, the transaction fees went down a lot. Coincidence?????
