An ideal currency doesn't exist in real world and bitcoin is not even close to an ideal currency!
There's no such thing as an ideal currency and bitcoin have a lot of flaws to make it as an asset.
Volatility is one and most of the people who engaged in cryptocurrency know that. But still people chose to deal with that because the profit in doing bitcoin investment is higher than you can imagine. When we talk about an ideal currency, it should be perfect, no volatility, no fluctuations and has no flaws. But in reality, that currency is non existent.
We should enjoy those cryptocurrency where we can get benefit from them and do not compare them based on their value because they have their own importance and prices depending on the market,.
