No, you shouldn't worry. Same thing happened about 2yrs. Ago shortly after the last major BTC bull run. The price drop dramatically (like from $6,000 to $3,000) and stayed low for a month or 2 but then it started to gain momentum again and as you know is now worth close to $58,000. If you're gonna get into the crypto game you need to be in it for the long haul to make a profit. I purchased about $200 worth of BTC during the last major bull run when the price was really high and then a week later the market crashed and I was left with almost half of what I initially payed, but I held onto it and now that $200 is worth about $2,000. I know it's hard not to freak out when the price drops dramatically but just hang in there and you will eventually come out on top!
