I actually really like this site - I hope they flourish for a long time.
in fact there are 2 possibilities here. Firstly you can invest (minimum $1 or equivalent) - earnings are accrued every 3 hours - are slightly different every time being the profit on "Trades" - and total ca 2.8-3% daily (Higher Returns on higher amounts). Withdrawals of accrued income possible at any time - Minimum withdrawal $ 0.10 or equivalent. (Withdrawal Proof of minimum amount herewith)
Even more interesting however is the Arbitrage possibility which is also offered on the site. Here minimum investments are 0.003 BTC / 0.12 ETH / 0.66 LTC / 150 XRP / 0.4 DASH or 7000 DOGE. The investment here consists of "trading" between what they show as BUYING and SELLING prices on different exchanges. These prices are updated every couple of minutes. Basically you choose your profit - check in their software what the yield would be (55% of profit goes in charges -45% to the investor) - examine the Delta - and go for it! Their software does not allow you to make a loss. Sounds complicated but it really is not. Every trade is different - and brings net (for me so far) usually between 1,5% and 2,5% profit. The "Trade" takes around 3-5 hours and can be inputted anew ( 4-5 times every day - meaning basically you end up with a daily profit of say 6%-12.5%. The profits and the principal from this trading system can be withdrawn at any time.
Basically the idea is to make a trade - and reinvest the profit each time - meaning the returns get better and better - until you decide to take some profit and withdrawal.
On top of all this the site have their own TOKEN - the MCOIN. You receive 10 MCOINS when you register - additional tokens for joining the Telegram, Instagram or VK channel - or for making a video - and also extra coins everytime you earn profit - which is of course several times a day. According to the site they are planning to introduce an internal token exchange shortly. Otherwise tokens can be exchanged for US$ or Crypto. 100 coins = $ 1. They are planing to get the MCOIN listed from 2022.
The referral plan is 2-level giving 10% and 5% on all deposits.
MCoin have already developed apps for ANDROID, IOS and MAC. (I have only tested the Android App - works fine)
A lot of work has gone into developing this site. Maybe there have been other similar ones before but I do not know of any.
It remains for me to say that I have no connection with the management or admin of this site.
