Despite its volatile nature, Bitcoin surely will always appreciate and thus, investing up to a half of Income is a wise one with future mindset.
Investing up to half of your income it’s not actually ideal , in as much you consider the bigger picture of Bitcoin in the future , you should also understand it’s a long term investment, so you are adviced to invest with your discretionary income, so that it won’t affect you unless you have other business and investment that can fetch you some money , if not investing half of your income may affect your accumulation journey or properly result to selling when you don’t have much money with you .
Yes, when investing in Bitcoin, having great enthusiasm is important, but don't let that enthusiasm overwhelm you and neglect your financial security. I believe investing in Bitcoin, or any other asset, should be done wisely and shouldn't be driven by greed, which can be detrimental. Therefore, what you did (investing in Bitcoin with half your salary) was certainly reckless and likely showed a lack of appreciation for the Bitcoin investment process you were about to undertake. Because when you invest in Bitcoin, you shouldn't forget about your needs, as it certainly requires costs.
So, when you invest in Bitcoin and start accumulating, ensure the money you invest is your own money. Or, you could also call it discretionary income. Because, if you invest in Bitcoin with discretionary income, you're likely to be able to hold Bitcoin much more optimally. After all, discretionary income is money that isn't allocated to any other needs. Therefore, when discretionary income is invested in Bitcoin, it will certainly be much better. But if you invest in Bitcoin using non-discretionary or hot money, I'm sure you won't last more than two months. Because the hot money you invest is essentially still part of your needs.
