For me it started off as fun until I realized the potential and big money I could get out of it so now its become my life savings for my future.

I saved bitcoin for my future and not for any fun or what? Because I know it will become 10,000$ in the near future.
aside from that it has a brighter future, which can also give to people financial freedom, savings and assets too.

Yeah, just consistently do it until your reach your goal and if you don't have any goal for the amount of bitcoin then it is better to have a goal so you have a clear path on how much bitcoins you want for saving so if you reach that then you will just need to make another plan for the possible things that you can do like investment or converting it into cash.

I do save bitcoin for purpose. I want to make it as an investment so that I can buy business related stuffs which is currently expensive. I'm expecting that bitcoin can give the profit I need.

Then it would be quite risky to invest bitcoin in the short term. For the long term I'm sure the bitcoin price will be higher than it is now. I also save a few percent of my bitcoin for the future

For me, too, bitcoin is a contribution to the future. And in a few years I will be grateful to fate for having made the right decision today.
Therefore, we must accumulate as many as possible of bitcoins

Yes, this is a good idea of holding the bitcoins if you have no need to convert them into fiat then should just leave them be in our wallet and shall sell them at a more better price when we really are in need of fiat and have no other option then only to sell our hoardings. But it is many times, explained here in future, we may not need to sell bitcoins as we will be having enough options to "use" bitcoins. So, forever we may not need to sell off our bitcoins.

People who are into bitcoins just for fun purposes may sell off for no reasons or just to have some 10% to 100% profits of their investment amount into bitcoins but surely they will regret for their actions later.

Agreed, day by day due to the increasing adoption and acceptance among the common people​the spending  opportunities​ have increased​ a lot. So whether it's fun or profiting everything needs to be made in a perfect manner without making unnecessary spending. Because more you hold more will be the profit earned.

You have a very good heart. Many people care only about themselves.
I collect bitcoins in order to secure a rich life. In my country it is very difficult to find a job that will give a good life. And that's why I earn on the Internet with the help of cryptocurrency

to collect, I still focus on popularizing bitcoins either online or directing them one by one either publicly or privately to this day
