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.
