It is never a 'bad time' to be investing in Bitcoin as long as you are looking at it from a long term perspective. While you aren't going to see the massive profits (and losses) like we saw in the earlier years like 2012-2013, you definitely want at least a little in your portfolio.
I don't know how many people have told me "I should have listened to you and put just a couple hundred into Bitcoin back when you first told me to."
But on the flip side, I have said that same exact thing to my friend that first got me into crypto.
