If we have 0.5 Bitcoin and 1 Bitcoin that are bought on same date then 'percentage of profit' on both will be same if hodled for same duration. If you don't have huge money to invest in Bitcoin then don't get discourage rather keep investing whatever you have. Of course the one who has more money can go for more aggressive accumulation. In the end, percentage of profit will be same in both cases. It's important to understand that Bitcoin is for everyone not just for rich guys.
Are you sure you have done this calculation well? Because I don't think it was calculated the way it was meant because there isn't how 0.5 and 1 Bitcoin will have an equal outcome of an investment because with Bitcoin moves and the one of 0.5 doubled to 1 Bitcoin the second amount of 1 Bitcoin will also double in price given 2 Bitcoin instead of the actual number it was meant to be so actually you can say that 0.5 of Bitcoin can be highly profitable in the future but doesn't mean it can be the same with the amount that's higher than that, actually a person shouldn't invest based on equality of profit with others but instead they should think on how they can grow there investment.
percentage is different from actual number. we can have the same profit percentage but because you invested more and i invested less our figures will be different and the one with the higer investement will gain more.
by the way comparism can will become a killer of joy. if i continue investing as little as $10-$15 a week after a long term will be something for me. it is about my investment not who can save one bitcoin.
