This is not the perfect time to sell everything, as price is not too high at a moment and even if it goes higher I will never prefer to sell all my coins, I will surely hold some of them for future.
People should not follow the OP's directions because selling everything can be risky and you can't probably be stable in your finance for years.
I would never risk so much money by selling everything and investing them in bitcoin because nobody guarantees that bitcoin price will increase and we can make profit.
