my personal opinion is better to invest your money, choose a long-term investment with little risk, or you can buy some bitcoins to invest it but bitcoin have high risk, as the price of bitcoin is very unstable and fluctuated, we will never know the price of the bitcoin in the future.
Yeah. That is the most obvious choice you'll want to make if you want to see your capital grow over the long term. When you invest into limited supply assets and commodities like Bitcoin and Gold, you can ensure your financial life in the future as they tend to rise in value over the course of time.
With Bitcoin, you can both save and invest your money into it, while being sure that you'll earn profit over the course of time, when prices start to rise. There are no banks, or middlemen behind it, so it makes it an ideal choice towards preserving your capital for the future. The only downside is that prices for the pioneer cryptocurrency, are extremely volatile, making it quite troublesome for anyone who would like to make short term profits. Due to this behavior, we cannot predict Bitcoin's value in the future, but as long as there is a wide audience giving their support, it will continue to gain traction.
Gold, on the other hand, may be the safest investment you'll ever make, as prices are relatively stable and it aims to appreciate in value as time goes by. As you said earlier, every investment has a risk, but as long as you manage to overcome those risks, then nothing should stop you from increasing your capital for the long term. Just my opinion
