prepare your bitcoin , we are getting rich when bitcoin halving . 
Actually, i also do the same like you. I have around 3 bitcoins right now and holding my bitcoins until the halving come. I think it's the easy way too get rich now.
I was amazed if someone could hold many bitcoin and can continue to survive until halving. usually people will be tempted to sell when the price pump. and it also happened to me. very unfortunate I sell at the price of $ 500 because of impatience.
you have to be more patient if you want to get profit
Yeah patience is the key to make profits in bitcoin, if you would have hold your coins at this stage then you would have earned huge profits, no issues learn from mistakes and don't repeat the same in future.
You are right, holding a good way of getting rich and if you are holding a lot of bitcoins for sure when the halving comes, as the price is going to increase you can earn from just like what happened for early bitcoin people they have done that. And I believe that it will going to happen again as history repeats itself.
