I didnt have those forks because I didnt own bitcoin then noob
But I had bitcoin on binance while it forked on Bitcoin GOD - and they never gave it to me so stfu.
Binance stated that they will give Bitcoin God and they didn't.
I holded btc on electrum wallet when btc gold went in - still didnt get it.
And actually Bitcoin has more chances to be 0 than 1 milion usd as you predict. They will just ban usd/bitcoin - and it will be worthless.
Just look at price when simple info like korea ban made to bitcoin - now imagine GDAX closes - BOOM
Having all money on btc is stupid - if it goes to the roof - with some daytrade of new projects I can do 0.5btc out from 0.175btc - it will be still much money. If it fails - I wont lose all - If I see good adoption of BTC or LN will not fail - I will go in hard.
