Here's hoping that the scaling debate will soon be resolved, so that small transactions get viable again.
which the main focus now is btc and yet it will also be moving to any alts afterwards so better to look for resolution rather than to make
speculations.
So far most alt coins are mainly traded by people who want to increase their BTC holdings. It follows that whenever BTC significantly drops or stagnates, most alts follow suit. The only alt that seems to be somewhat decoupled so far is ETH. Which is also one of the few currencies that bring something new to the table. Disclaimer: I haven't been following alts lately so I'm only familiar with a handful. Most of my conjecture is based on past price movements and not on fundamentals.
