We always have the chance to invest in bitcoin. We should not even feel worried about that.
not anytime because not all times btc is affordable . there are also times that we dont have an upcoming events like what we have this year which was halving . if people is excited for some events they will prepare and start buying btc but if there is isnt , i dont think the buying rate will be much bigger so you should also expect a low pump for btc . still up to you if you think investing anytime is beneficial for you especially if you will be more foccused on using your btc for paying or you are willing to wait for more upcoming events .
