These kind of investors are people who have studied Bitcoin and have seen that come rain come shine, Bitcoin still remains an asset and a great one for future gains. And you know, what you have seen, tested and confirmed, you follow it with a different mentality. Despite its volatile nature, Bitcoin surely will always appreciate and thus, investing up to a half of Income is a wise one with future mindset.
It is problematic and misleading when you say we should invest up to half of our income in bitcoin because the statement can mislead newbies who are just starting to accumulate bitcoin into using the money meant for their expenses to invest in bitcoin, and when it is time for them to solve their expenses, they will have to sell their bitcoin in order for them to solve their expenses, and it will cause them to be out of accumulating bitcoin. Always use the right words whenever you are talking or discussing Bitcoin so that newbies will be well guided into using the right funds when they are investing in Bitcoin, which will aid them to remain in the game for the long term. It is better for investors to accumulate Bitcoin with their discretionary income since Bitcoin is a long-term investment so that they can be patient enough to hold their Bitcoin investment for 4-10 years for their Bitcoin investment to compound very well and give them a good profit when they sell it.
