When you invest in Bitcoin investment is up to you, but if you invest in the right market and hold that investment for the long term, your chances of profit will definitely be high. If you don't want to invest right now, you can certainly wait for a big dumping market. Moreover, you can take another plan, in which case you can divide your investment into different percentages and invest in DCA method, in which case you invest in different markets, at different prices.
Apart from having to be smart in looking at market conditions, actually investing doesn't need to be so difficult to understand as long as someone who wants to become an investor already has the capital to invest in Bitcoin. Because investment is a very simple thing for everyone to understand as long as they are mentally strong enough and know how to use the method you said.
I also quite agree with dividing investments into different percentages, because that will direct each person to distribute their money to several things they will do at one time. Because investing in Bitcoin is more suitable with the money we specifically provide for this without sacrificing the money we want to use elsewhere.
