Although , this type of investment has high risk , In my personal experience it pay as promise and my investment returned within 26 days. (I initially invested $25 around 0.009btc and return it back) so,You will get guarantee high return (3.5%+ daily or 0.16% hourly) with cutting edges mining instruments https://futurecoins.io/?ref=abintl and best part you will withdrawal your principl after 24hrs and withdrawal thresholds is 0.0005 btc only. these systems have done very well so far but keep in mind they are not proven over time and could be reverse at any time in the future
