In the recent weeks we have observed the implementation of Lightning Network in the transactions of Bitcoin.
No major wallets have implemented it, so it is having pretty much no effect on the fees.
Currently, Bitcoin fees are very sporadic and unreliable. Looking at one day and saying "hey, the fees are pretty low today" really doesn't help Bitcoin to become more useful as a payment system.
The Lightning Network and wider SegWit adoption are still fairly long-term expectations.
Those coins that you're talking about are cheap to send but they are also cheap to buy. If you have a crypto coin that costs 0.1 USD per transaction but the coin costs $100 it's nothing special.
No. The cost is the same for a new user regardless - this would rely on people all buying an arbitrary amount of Bitcoin in order to begin spending it.
