I'm very sure even satoshi nakamoto never believed Bitcoin will become this big, Bitcoin is growing day by day and with the way Bitcoin is growing if it continues like that which I'm sure it will, Satoshi Nakamoto may one day becomes the world richest man.
He may have foreseen some of this things and that is why he made himself anonymous while allowing the network to be decentralized and not only him having the full power over it. Don’t you think must of the mystery surrounding Bitcoin are all foreseen by him and that is why it lead the foundation in this manner to still make it trail on this path. He owns the larger number of bitcoin to be ever mined, which makes his holding a reserve for bitcoin to keep its price never going to zero. Only him won’t have control over it, which won’t make him alter the network because he’s the inventor of it. Everything is just too perfect to find a fault in his innovation and blame him. It does look like he won’t be too surprised to how far Bitcoin has come today.
Anyone who is accumulating and holding Bitcoin can never regret it, Bitcoin has not reached half of it's growth meaning Bitcoin will keep growing more bigger and better.
This will forever remain a speculative stance, no one can tell how far or how well Bitcoin can go but base on the current data available and information to predict what the future of Bitcoin holds, they all look positive that Bitcoin will continue to grow and make all time high again in the future. This technology don’t looks like it’s going to fade, it’s going to be a continuous growth without doubt.
