Will satoshi come back and give his 1 million btc to users of this forum if BTC

Any invention that is able to survive for more than a decade can be considered successful. btc has already achieved what it was intended for even though it seems not to be generally accepted (thanks to the gov). it's popularity and evergrowing awareness is its great success.
And don't expect to receive anything from satoshi bro, the days of getting free btc already long gone, now you have to really work for it or save to have it.

if BTC is no longer valuable and becomes like token?

I wouldn't have thought it would come true without a major catastrophe. Bitcoin has an already strong user community and I don't think bitcoin will ever become a completely worthless asset and become a token. Bitcoin unlike tokens, bitcoin is not dependent on any other blockchain and bitcoin does not need any other token or altcoin to have value.

IF his project fails what would he do with those coins?

I will answer with one of the most phenomenal questions whose answers are only guesses because no one knows for sure, do you believe satoshi are still alive?

^ This is impossible why?
The actual BTC circulating supply is not exactly that amount of 21 million which means others are holding it and while some other was stuck/lost on the wallet and it should be there forever. I think that will not hap[pen that BTC losing its value, it becomes a worldwide adoption, and many people now holding BTC waiting for the right moment to sell their BTC to have and get their profit.
However in the satoshi story, that is different here, that dude will never come back anymore and we should respect that stuff. He/she/they are in danger in the public,.

Bitcoin will never be like a token, and will not probably dead.
I don't think that Satoshi will come here even in such a condition. Although Bitcoin will be still valuable and increase muc or dead, Satoshionce is hidden and will be always hidden.
But Think that Bitcoin will not be dead. If this is dying, we may not be in this life again, and because that may happen hundreds of years later or even to be more worthy again

Reading through the comments, I see that many other users have explained to you what a token mean.
Whether bitcoin fails or loses its value, it will forever continue to remain a coin and never a token, this has nothing to do with its value in dollars.

I have heard that he mined 1 million btc and was hoping that BTC would have converted the entire financial system in 10 years.
IF his project fails what would he do with those coins?

First, I agree with @NotAtether that it is likely that Satoshi (who ever he is or they are) is no longer alive, it's a probability and not a certainty, might be the reason why the said mined coins has remain untouched for several years.

Secondly, I don't want to categorically say that bitcoin has grown past the point of failure, because we all know that everything is possible in this space, but like what NotAtether said, I will rephrase it to - if bitcoin fails, we all look for it's alternative and move on with that.

But another question is, what level is/are the chance(s) that bitcoin might fail?
My Answer : very slim (I don't want to say it's impossible since I don't know what the future holds).
