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 necessary to sell all your asset because there are still a lot of ways where you can earn bitcoins. You can work on bounty campaigns or invest btc or altcoins and start trading in the market, if you are wealthy enough and have huge amount of capital then you can build your own mining rig and earn coins passively.
