Usually if a guy started investing in bitcoin towards the top, he would have had ended up bring ing down his average cost per BTC a lot if he continued to buy for something like 5 years, or even if may be he bought for 3 years on a weekly basis with a combination of DCA and perhaps lump sum buying during times that he might come across extra money. He could also buy on dips, though it may not necessarily make much difference if he might be regularly buying... and just riding out the wave... so even a guy who came into bitcoin towards the top at $1,100, he may could have had an average cost per BTC around $400 to $600 by the time 2017 came. Similar a guy who might have had started buying bitcoin around $19k in 2017 might have had still ended up with an average cost of BTC that is around $7k to $8k by the time he gets through 2020.
I suspect the less disposable income people have, the more they feel inclined "to time the market perfectly". Yes they should not do that because without a good portion of luck, nobody is going to time it perfectly. But it is this desire to see their holdings grow in dollar value more quickly.
I do not think this is entirely right because timing the market is simply a bad habit people have that does not depend on the amount of money they have. It is a wrong way of going about Bitcoin buy because it tends to appear like trading in practice and not the practice of someone buying to HODL. Take for instance, if someone is applying weekly DCA of $20, and another is using the same method for $200, both have different amount but they will buy without bothering themselves what the price of Bitcoin is because their method of purchase require that they do not look at the price at the time of entry but should rather maintain consistency. I hope you understand now that the method you adopt to purchase Bitcoin matters a lot and will most likely determine how you act towards the market.
Not everyone will need Amazon or Apple shares in their lives ever, but I would not rule out that everyone will one day need at least a little bit of BTC for whatever purpose. It is a whole different type of investment with a more complex investment hypothesis than any other asset class.
Again, I still doubt your position here because my understanding is that Bitcoin is the easiest and straightforward asset to invest in, no bureaucracy, Just get your money, create your wallets and accounts, proceed to the exchange either DEX or CEX, buy and withdraw to your private wallet, hide it their and HODL.
It may sound funny to you but I want to confess that up till this moment, I have not understood what I should do or how I should go about buying shares in Apple or Amazon. I don't know if it is because I have no interest in that since I consider Bitcoin to be enough for me. Whatever it may be, I still believe that Bitcoin is the easiest asset to invest in and the best asset to HODL.
