We must acquire knowledge about Bitcoin to invest. Because only when knowledge about investment is gained we can use it in the work of holding. People are lazy that's why they face loss today because their motive is to earn profit. Investors become reluctant to sell when little profit is earned, as they have not acquired the appropriate knowledge. Due to which even after investing they cannot sell at the right time due to which holding is not suitable for them. So I think one should learn risk taking by gathering proper knowledge and using DCA method strategy with patience and holding for long term.
Investing in reliable bitcoin like bitcoin is not risk of losing money so we can invest in bitcoin. Besides bitcoin we can choose some coins to invest from altcoin. But investing in altcoin is more risky than bitcoin. Again bitcoin's If you invest in altcoins, you have the opportunity to make more profit.
IMO for this although it can be done, I think it would be better not to do it than you torture yourself with the wrong choice.
Many people consider having bitcoin and altcoins as a form of investment as something that must be verified, but for me this will only be a waste of time. it is undeniable that there are many people who consider some altcoins that are considered to be one of the viable alternatives for investment but without thinking about the far greater risks that you cannot even reach then it is better not to try it because this will only be a naivety.
The risk is still there but the difference is very clear when we have a smaller level of risk in bitcoin why should we try to do a big risk in altcoins.
