As a newbie who has a little knowledge of cryptocurrency but much interest in purchasing bitcoin for a long time Hodl, since the purchasing capital is not included in my spendable budget and the price of bitcoin is not very high at the moment 16k, what should be my fear?
Pls, advise me.
The only fear you should have is losing your wallet, which you won't if you keep back up your wallets and keep it safely. If you were planning to hold short term, you should have fear about about making losses because the market is very volatile and the price can take a huge dip within few minutes. But since you are planning to hold long term, I don't think you should fear anything. If you are still scared, look at the chart and you will know what you are doing the right thing. But only invest what you can afford to lose. And better learn a little about crypto currencies. It will help you make investment decisions.
