It is a good news and slowly it will increase the demand for bitcoins. But if you want to invest money then no one can suggest you correctly when you can start. So the best time is now not later. If you have decided to invest in these cryptocurrencies then better start today with a small amount and slowly build it in the longer run.
As long as the bitcoin's price is increasing, then I could say that every time is the best time for you to buy bitcoins, as soon as possible, the better, Why? it is because when you are going to buy bitcoin in a specific price, then the earlier you are going to buy the more profits that you are going to have in the long run. But if you are going to hesitate and going to ask always when is the right time, then you are not going anywhere, you are not going to reach whatever you are trying to reach.
