Now I want this to be for my savings and maybe more. I see some for investing, I really need to read more to know about that investing.
It is a saving and also an investment when it comes to future so it is better that we keep our bitcoins safe in a cold storage and wait for the future, so basically at present I only use bitcoins to convert it to fiat when I am need of money, rest I have kept safe for the future.
That's the great idea. Because bitcoin not in using phase. It's still in saving phase. When the prices hit an unimaginable price or more than 90% all time bitcoins are mined off, then the time is coming for spending bitcoin. At that time everything would be available for bitcoin. We do not need to convert into fiat at that time.
