Bitcoin is a long-term investment, not a get-rich-quick vehicle. You need to clearly define before investing, if you just want to buy and wait for it to increase in the next few days then I advise you not to invest. If you have a long-term goal that can be measured in years, maybe two or three years, now is a good time to start buying. Bitcoin is trading around $20k, which is a pretty good price compared to recent ATH, you will benefit greatly if you buy now and hold until the next bull season.
