For sure, you are absolutely correct there is not time someone will start Bitcoin investment that he or she won't make it provided they are doing the things that is required of but having a good source of income doesn't mean one will accumulate enough Bitcoin fast in their portifolio rather what will make an investor to be more fast in their accumulation is how many percentage of their source of income they are using to..., some people have a good source of income but they are just accumulating very small and I don't blame such people maybe they are just being careful not to use what they are not meant to..., but as long as they are consist they are going to make it for sure.
Accumulate the amount that suits you right for example those who receive huge salary and yet fail to accumulate huge might have bigger responsibilities. If you observe clearly bitcoin investment is not all about monthly or weekly pay measuring it with the amount used for accumulation sometimes we just have to take responsibilities first and other times we invest using a good amount. All what an investor needs is a good cash flow that can keep their investment going for long secondly a good management is also needed.
There are many investors who fail to invest in Bitcoin despite earning huge amounts of money. There are many investors who are encouraged to invest in Lump sum. They think that when the Bitcoin price reaches their expected level, they will collect Bitcoin which is a completely wrong idea. Those investors may find it difficult to hold bitcoins. Those who make low incomes but consistently do DCA to hold bitcoins will be ahead to holding bitcoins. There are many instances where a person earns a lot of money but fails completely to hold Bitcoins. To invest here one must take bitcoins responsibly which can help the investor build big assets after a long period of time.
