How much % you invest in Bitcoin is completely your personal decision. As you mentioned, you will not be willing to invest more than 10% to 15% in a volatile asset like Bitcoin. Every investment has risks, if you mean investing in gold, then I would say that Bitcoin has become a much better asset than gold at present. The future of Bitcoin seems to be bright because, every person now wants their financial security and financial freedom. For this financial security and financial freedom, Bitcoin is the most reliable and safe asset.
The main reason why Bitcoin is more of a better asset to invest in right now than gold is that it's still far away from it peak price, it's more like a 17 year old that still has a lot of life ahead of him, unlike gold that is closer to it peak price, and has been around since from the beginning of mankind. So it's because of that Bitcoin is more of a better asset to invest in than gold.
. I believe that when you are able to deal with the volatility of Bitcoin day by day and are able to build complete faith in Bitcoin, then you will decide to invest between 40% and 50% of your total wealth in Bitcoin.
This should never be taken as a financial advice because it's a bad advice. If you invest 40-50% of your total wealth as you are proclaiming, you are actually going all in on your investment, or you are investing with what you cannot afford to lose, which will compel you to always be in a state of panic anytime their is a dip in the market, so this is a terrible idea bro.
