You should consider a few things when you are doing the examination. Since when did price volatility become an issue for Bitcoin? One of the biggest reasons why so many people are interested in Bitcoin and cryptocurrencies in general is the price volatility which provides an opportunity for them to earn money by buying them lower and selling them higher, so I don't see this being an issue but it's a property that makes them so popular.

Scalability is an issue, no doubt, and we can often see the negative effects of this issue when the network gets congested whenever there are a lot of transactions being made because the block size isn't enough and the gap between blocks being mined is a lot compared to other blockchains.
