I personally feel like BTC can make a last ATH(for now) from here... SO my advice for beginners is to not buy BTC BUT buy any good health ALTCOIN(XRP,TRX...so on) the reason is according to my past data analysis BTC move will be 20-25 % but alt coin can give significant move of 3x/4x/5x... Also make sure to exit at right time... goodluck....HOPE it works....
