Solidtradebank.com was listed by ISA on 12/Sept/2018 in Incubator section thanks to extremely long lifetime - since 2013. I played it in the beginning, but then left it for 5 years. I am playing it again since July 2018.
Please keep in mind that you can deposit just via PM or PY, other payment methods are outdated - intentionally, to keep the inflow low and extend the lifetime. I am curious how long will it last, or will be redesigned ever?
Update: sure, nice redesign in the end of 2019
Update: decreased ROI: 0.2% for 25 business days (previous daily plan: 0.5% for 20 b.days) 2020
Update: so many cryptocurrencies were added, but USD remains the main currency for all (21/Dec/2021)
Update: PM is disabled, active PM balance can be exchanged just for TRC20 - Thron. And withrdaral fee was added - 1$ (Feb/2021)
Update: referral rewards was increased from 0.5% to 3 levels: 2% - 1% - 0.5% (3/Sept) This day I was rewarded by a Bronz level, so I am able to give 3% from your deposits back to you - for my first level referrals.
Update: some investors reported withdrwal limits, they are able to withdraw just tiny amounts. I do not recommend to invest! (16/DEC)
