BTCI have to sell all assets, stock, sell the house, all buy coins, within three years, killing one coin will not sell, this is my confidence in bitcoin.
What do you think about the growth of bitcoin?

It is not a smart move to sell all your assets and other investments in exchange of buying bitcoin, that is a very risky decision since you are a late bitcoin adapter. Waiting for 3 years to grow your bitcoin investment does not guarantee that it will gain a profit of more than 1000%. Unless if you start investing bitcoin 3 years ago where the price is less than 500 USD. Now that you want to buy bitcoin at a price of 7000 USD, probable gain will be at 300% conservatively but it is still not bad.
Smart people who buy bitcoin before are also smart investors because the diversify some of their profit to buy good performing altcoins in order to place a better position, prepare and anticipate whenever bitcoin goes wrong.
