Why not just use bitcoin?
It is useful however for a value store. Eg. You can't rightly trade units of gold 50,000 times per second, but it's a good bet that if you buy some and stow it that it will at least hold or even appreciate in value.
If you want to transfer the payment for your home, then it makes sense to use bitcoin, but today most people sell their btc for daily expenses, convert it into a faster crpyto (like Ether or litecoin etc) and use that instead.
Bitcoin maximalists don't want that, but I am quite comfortable with this scenario.
Transactions are included in blocks in an auction system, where people bid for the limited amount of blockchain space available. If your bid is high enough, your transaction is included immediately.
There have always been far more people who want to get transactions mined than there is blockchain space. You can find gigabytes of valid transactions that people have broadcast for various reasons, including deliberate DoS attacks, and extremely low-value applications like inefficient timestamping protocols. Any website that makes claims like the mempool is "100MB" is simply incorrect.
The supply of space fluctuates randomly, as block creation is a poisson process, and demand fluctuates for other reasons. So if you have a lower bit you might get lucky in the future. But that's no different than the prices of any good subject to natural supply and demand fluctuations.
You're just explaining my point in more detail, but not disagreeing with it.
My point was, "Bitcoin can't be used for kik tokens because it has limited space and kik transactions are not justifiable for this purpose (via the high fees)".
