First of all if I would win 100BTC I will be in heaven. I will transfer 10 BTC to binance exchange and wait for the next bull run.
Check them out at the right moment so i can pay my apartment to the bank and get a new car, wile i put the rest of the 89 BTC in to a cold walet and keep them for my little 1 year boy. And I'm thinking they will be an awesome gift for him at the age of 21.
And at last with the other 1 BTC i would investing it in some alt coins so i can increase the income.
Sorry for bad grammar but English is not my native language :).
