While there is a lot of noise around bitcoin reaching $10k, Litecoin has quietly hit triple digit. It is above $100 now.
I believe that once bitcoin goes mainstream and people accept digital currencies, there will be scope for more than a few currencies. Bitcoin will always struggle with scaling and cost is prohibitive for day to day minor expenses. Litecoin / Dash or Bitcoin Cash will come to the rescue. I particularly like the team behind Litecoin and Dash. Both have huge potential and it is a matter of building ecosystem. Litecoin has a leg up in some aspects while Dash is building amazing user interface. Bitcoin Cash is pulling its act together and catching up fast as well. Who will gain more traction is difficult to say but there is definitely room for some low cost fast cryptocurrency and something has to bubble up.
