Yes it is never late to buy bitcoin. Because when i bought it was at 3000$ and I asked the same question but today is almost double price. So after some time u will not regret to buy it now
I think that those people who will not buy bitcoin right now they will surely regret tomorrow. We already missed opportunities when the price of bitcoin was trading below 300$. I think it was the best time but now when we think about it it was really a great opportunity but we really missed the opportunity. But i think still it is good to invest and should not miss any more opportunity.
