I think that it's a good time to buy Bitcoin especially during this sideways movement.. Be wary if it breaks support though, I would always be on a lookout.
Right now, the market value of bitcoin is at around 13k $ which was previously at 20k $. So, this is indeed a very good time for investing in bitcoin and then buying of more number of bitcoins in case you already have some bitcoins in your wallet. Opportunity knocks at everyones door once. So now is the time to cash that opportunity in the best possible manner in order to have better living.
