As we know blockchain is currently facing size related scalability issues.

Then looking at this list of other coins and some of their technical stats:

How do you determine which are less likely to suffer some of those same problems?

It is quite simple, you take the block sizes, you compare the miners hash rate, you take the difficulty in check and when take a look at how quickly you can fill up that block size and mine it as quickly as possible you see that confirmation times are quick or not. Doge for example has huge advantage over anyone else whereas bitcoin is the worse.

Why? Because bitcoin has limited supply and huge demand whereas doge has huge supply and limited demand.

Okay, so then assuming equal demand,
is it possible to determine which coins in the long-term will not suffer the problems with confirmation times & clogged network that BTC is facing rigt now>

Fine. Put $50 into all alt coins and pray.
