Now is actually a good time to buy bitcoin because of the dip and it still hasn't gone up so investing now is definitely a smart move.
Don't let anyone convince you that it's too late to buy bitcoin and invest, it's never too late to start
Yes that's true!, it is not too late to invest in bitcoin even now bitcoin price is on the dip, bitcoin will still continue to rise and back again to $20k usd or more this year.
Consider this drop in price of bitcoins as opportunity that you could buy bitcoin at a cheaper price and in my opinion, this is not late for you to invest bitcoin. You may check out the price history when it started and how it pump to nearly $20K USD in the last quarter of last year 2017. I do believe that bitcoin is going to make a bullish run in the coming months, so let's hope it will come soon.
