at this moment i think so. bitcoin is now much stable coin than last years. last year people thought it's over for bitcoin but we all know bitcoin didn't come for gone. now after couple of correction bitcoin too much stable than ever. people start invest on bitcoin and market going in green again.
Year 2017 was the biggest rise of bitcoin. Last year that is 2018 was more or less a stable phase at 6k USD and the long bear market. What we talk about as volatility the daily change in price during last year was around 1-2% and that does not make the price too volatile. What was previously going on can be considered volatile at times but not always.
I dont think this this is a bad time to invest but a good time but today the market was a bit greed so probably the good price to enter would be 5.5k USD is that is touched.
