500K USD is going to be an EPIC! I'm keeping my coins on my wallet incase this will start going up to just 100K, i'd be very much grateful to who ever pump it. It might just be worth keeping BTC than investing to some ERC token which we thought would be huge like ETH.
That's a very short amount of time to see bitcoin go up at $500,000. I'm not telling that it is impossible to happen but why that's a very short time because I was thinking that for 3 years bitcoins price can be stable somewhere at $10,000 - $50,000. Yes that will be stable at that rate but saying that it will go $500,000 maybe it happen too but just for a while then it will go down again.
