There are many people that is saying that the value will not even rise after the halving and that can be bad.
When the big crash comes, I will sell my altcoins and buy lots of bitcoin. It is a good way to make money.
The big crash won't happen. You can buy and sell altcoins when the price of altcoins continues rising. This might help you buy more and more bitcoin rather than expecting a crash.
The bitcoin crash will not come as long as there are not big pumps. The slow rise will be more beneficial to the bitcoin.
And I also know that the halving is coming but it wont reach that high in the future so we have to be patience and that is the only option.
