I really like this part quoted boldly. That is exactly what I want people to know about bitcoin. But the way investors are going about this holding bitcoin is becoming like it’s even a crime when someone spends part of his bitcoin, and I really do not like that. I mean it’s even decentralised such that you have no business with anyone or any authorities. so everyone should do what they like with their bitcoin. As long as you’re using bitcoin, you have just done a great service for yourself by having and alternative payment and transaction methods.

Yes, this is what is called freedom to use your own assets without rules from other parties, because you are the one who determines it.
As I said, it's like having your own bank and you're going to own the rules and power, no other party as long as the wallet you use can be completely controlled by you.

Early investors have probably saved enough number of bitcoin so spending a little amount of bitcoin won't make a huge difference. But for those who have just started buying and holding bitcoin, we can't expect from them that they will participate in promoting bitcoin as a payment method. Of course, they also have their own goals and plans for bitcoin. They will eventually spend it but right now, its not their priority but accumulate more bitcoin instead.

Certainly you are correct no one else needs to worry about how people will spend their bitcoins, everyone is using bitcoins for different purposes as in my opinion it is already clear that many are turning to bitcoins for profit, some are using bitcoins to hedge against inflation, even it can be said with certainty that there are many people who also consider Bitcoin as a means of payment, some see it as a store of value and many see it as an opportunity to make money by storing bitcoins for the long term but that doesn't mean everyone is using bitcoins for the same purpose.

The features you mentioned prove that Bitcoin is decentralized and is automatically managed through an open and independent network as we know it is not controlled by any central authority allowing everyone to do whatever they want with their Bitcoin.
