It is good that Bitcoin is now being talked about, low income earners can now invest as opposed to gold and and other forms of investment that requires large amount of capital. This is not just a comparison, but a reality and everyone is entitled to choose what they prefer.
As for volatility, many still fear volatility and the bear season till date, especially this same low income earners. Many who understand how Bitcoin works do not necessarily need to panic. That is why to overcome that fear, they have to take out time to understand Bitcoin very well.
Anyone who chooses gold over Bitcoin is not a hater, he understands gold better and is more comfortable dealing with the risks involved with gold than Bitcoin.
Investing in Bitcoin requires that you know it would not suddenly stop being volatile just because you're a low income earner. This means that you've already prepared your mind for what's going to follow and I regard the volatile nature of Bitcoin as the thing that makes it exciting, different from every other form of money.
People who are now including Bitcoin into the equation have now understood that it's something worth talking about, it has proven that it deserves to be considered as competition alongside Gold.
Some people refer to Bitcoin as the digital gold, while others would prefer it in it's raw form so it's a matter of choice.
Bitcoin is in no competition with any other asset class or currency, it is in its own league. People will invest in bitcoin because it has value, it hedges against inflation and they trust it, not because they feel it is better than gold. There are some gold investors who are doing better than Bitcoin investors. The most important thing in choosing your preference amongst these two is in you assessing your risks tolerance and going for what suits your personality and risks tolerance.
