The core question here is; what triggers you to invest?
Money. Profit. To support the coin itself.
Me spending some money, and investing in Bitcoin doesn't mean that I'm on it for the profit only. Although it's the main reason why I'm investing, I also plan to use Bitcoin to buy some things in the future when the transaction fees are low, and more establishments are accepting it. I think that's a way of supporting the technology behind it. People are investing for profit. People are investing because they believe that they will get more money when they invest in it. This is the reason why Bitcoin is more of an asset than a currency, and there's nothing wrong with it. It's just that, the main purpose of Bitcoin which is to be a currency without any third-party involved is slowly fading away. Can't blame other people though.

However, I'm working hard studying extensively to understand the market. I feel this great joy when one post his first time buying Bitcoin, I get this great zeal to buckle up and nurture the feeling of investing too, believing that one day, that which triggers the feeling to invest will come to manifestation. I envy every first timer Bitcoin buyer, cos I'm looking forward to being like them in no distance time.
Save some money, learn how to buy Bitcoin, and also learn the basics of not just Bitcoin, but cryptocurrency in general maybe.
Do you envy them? Your time will come as well. There will be a time when you will be the one to buy Bitcoin, and some people will envy you as well. Take your time. Investing isn't a race. If you don't have money for now, work more so that you can have money to use to buy.
