I am not using any other crypto currency at the moment, but I don't think any of them will ever overtake bitcoin. Its the standard of all, its like money now, do you see money competing with anything else? I really don't see that. So I feel bitcoin will hold it own in the market and would probably keep growing.
I agree to this idea. I see bitcoin is so promising that even other fiat currency are beaten by it with reference to its value. It is still my favorite crypto currency.
