prepare your bitcoin , we are getting rich when bitcoin halving . 
Price will higher at halving for sure, but to get rich with bitcoin we need to have huge number of coins but you can expect good profits from the coins that you hold.
Yes with halving we can get big profit and for getting more we have to buy huge number of bitcoin, but those people who cannot buy more bitcoin do not have to worry as with their small amount of bitcoins they can earn a better amount of profit and then with that profit they can start a small business, so they will also be rich.
There i s some profit to be made with the halving, but don't expect to get rich or earn a fortune. Bitcoin now is fun because it can be profitable, but the main goal of bitcoin is not to make people rich. In fact it's about fast and anonymous transactions. And yes getting some starting capital for a small business, from your profits is an excellent idea.
