Bitcoin offers equal opportunities to the people. That’s up to them how they will utilize bitcoin, it may be as an investment or as a currency. But the fact remains that bitcoin is still expensive, and those who have huge amount of earnings will have more chances to maximize their investment, while those who have limited funds, will only start a minimal investment and I don’t see any problem with that. After all, bitcoin will grow in time, as long as you keep hodling your coins.
However, equality in the sense that people will have fair share of investments regarding bitcoin, that will never be possible. Fortunate are those who have unlimited flow of income, but even for those limited amount of income if they won’t stop doing DCA regularly, in time they will still accumulate a good amount of bitcoin in their portfolio.
I think OP is talking about equality in the sense that everyone would have equal banking rights and the opportunity to utilize Bitcoin as a payment system and as a way to become their own banks and need no third-parties such as traditional banks because a very large percentage of world's population is unbanked, which means they don't have a bank account because of the high requirements and rules set by the banking sector. I somehow agree with him but not totally, and I'll explain why.
The reason why I agree with him is that anyone who has money can basically buy and use Bitcoin, there are no restrictions or anything like that, but then comes the question of how they are going to use it, because Bitcoin is not like a bank where human operators are sitting doing all the work and helping you with everything, in Bitcoin, a person has to do everything on their own, and one single mistake can cost you all your money when making a transaction. So these challenges are the reason why not everyone can have access to Bitcoin, thus there can never be equality.
