Buying Bitcoin every month is not really necessary. You had an opportunity to buy when the price of Bitcoin decreased due to the pandemic. The price dropped to as low as $3,800 and even below that, and that’s the perfect time for anyone that wants to invest in Bitcoin, and do so with a huge amount of money. Now the price is going up and if you didn’t you buy you have missed out.
You can still get in at this time and if you’re lucky you will make profit. The halving is already close and I don’t know where the market will be heading to after the halving, whether it’s going to drop or keep going up. Let’s wait and see.
