Even you are new member on this forum you decided to respect to forum rules. Investing in cryptcurrencies are dangerous because markets are volatile and noone knows what will happen in future. Specially making big bucks requires experience and knowledge in this field. My advice is to keep researching among projects and choose best ones for investing big amounts.
