The best time to buy coins is over, buying coins now will or can put you in trouble, we can say that Bitcoin will keep surging and bears may take over the market, that will bring a huge loss, investors should know when to jump right in and buy to hold
After the flash dump from 12k to 10k5 today, my advice to you guys is don't buy anything else except bitcoin. Now is the showtime of bitcoin and the others will be dumped anytime.
I'm still doubt in buying since we don't know til how much it will dump, but it's definitely the time to monitors it and see whether there's a room again to pump into 12k as it falls too much in just some hours. Will keep waiting to sell again as I missed the chance earlier or to buy if ever it falls again.
