i had invested in insurance this is best investment in my life. actually i invested some amount of money in real estate but i got loss in that field, so next i decided to invest in stock market,  but in that field i seen more losses. then i decided i want to invest in the bit coins it is best and secure me and my family. now i feel very happy, and i had no tensions now. so my present preference is bit coins only. it has more demand right now. next few years it's price increase so day by day bit coins get more value. so my preference is bit coins only.if i have possibility i want to invest in etc also.
