That's my story. Been around since 2012. Lost access to everything multiple times when laptops randomly decided to kick the bucket.
$1M BTC is certainly possible. I remember when it hit $1000 and was thanking my lucky stars I could convert my Second Life Linden Dollars into BTC. It hit $20K and I thought this train was only getting started. $100K seems all but guaranteed. Probably will see $200K this bull run, maybe even $250K. $1M may require another cycle or two, so 4-8 years, but it can get there, especially if the fiat currency system implodes at the end of the 4th Turning and into the new 1st Turning.
It seems like a no-brainer to open up a 5x leveraged position, with enough dry powder on the side for a 50-60% drop just in case, and ride it to $1M if you trust the exchange and aren't selling the farm to do it.
