Your advice will help me to be a good BTC depositors to explain more clearly. I may be a little wrong in explaining but what I want to say is that a new investor should buy aggressively from his disposable income and not rush to make a buying decision through market analysis. Aggressive buying during high BTC prices may not be a good decision so I would at least start with small savings (DCA) method. There should be no mistake in depositing BTC from discretionary income aggressively or (DCA) and not regret it even if the price drops further. Although the chances of dumping too much are very low. The money I can lose or even if I am stuck in the portfolio for years will not have a negative impact on my general lifestyle. If I had floating disposable cash fund. BTC allows me to be optimistic to deposit more when credibility is high as long period.
The easiest way to invest is to start with the DCA method. I will not invest the entire amount of money from the money I have to invest, but I will keep some money for myself so that if the invested coin dumps after investing, I can use the money to recover the loss through the DCA method. Those who are smart always invest through the DCA method. And those who invest in a new situation often suffer from big losses due to not understanding the DCA method.
