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.
We will increase our profit opportunities if we invest with knowledge, that is the key word. If we invest without knowledge, it is tantamount to digging our own grave. Why do I say that? Yes, because if we invest without knowledge, we will be easily influenced by situations and even other people. For example, when bitcoin is declining, FUD will always come and I don't think it can be stopped, and when we have no knowledge then we will be affected by it, by the bad news that is spread and in the end we will withdraw all our money that is in bitcoin even in a loss. And that will not happen to someone who has deep knowledge about this bitcoin investment.
