starstarstarstarstar So many investors are confused and go into deep research, for a trusted and legit platform to trade and invest in. I was also looking for the best until I read good reviews and recommendations about Lady Maria. Her great skills in Forex and Crypto trading made good profits for so many in their trading account. I was amazed how many Investors wrote good comments about her. I contacted this amazing account manager Lady Maria and invested with her. I earned a very good profit and made my withdrawal successfully directly to my bank account. I invested $500 and made a profit of $7,000 within 5 days of trading. I am very happy to have met her, I made my second withdrawal and I now earn good profits working at home. I know this is inappropriate but this is my little way of showing gratitude and appreciation to her. If you wish to invest you can contact her via

starstarstarstarstar It came to me as a surprise after being reaped off by all those so called expert traders online I finally met with a very skilled and experienced trader who knows how to generate huge profit under a given period of time. I made my withdrawal of $6,500 after my first 7 days of trading with the little minimum investment of $500. I’m so happy Lady Maria, Thank you for your good works and for never failing the trust I have on you.

starstarstarstarstar I lost my money to a scammer who send me an email link of Blockchain with keys to open account. I would blame the Blockchain responsible for allowing such loop holes that allows any scammer to source keys from Blockchain and send it out via email to open account. I can say 100% that Bockchain is not safe place to store your cryptocurrency.

starstarstarstarstar My balance was zero when i logged in yesterday. I been contacting Blockchain to find out why my balance is zero and all my transaction records are missing.This is what Blockchain is all about. I think this was a inside job.No sympathy or support from customer service rep Jade.

Investigate also my ticket number 1405241 because it is not my fault and no longer blame me for taking viruses because I use a computer for my work with high-level security.I thought it was the biggest trust in the market and what happened?Javier Gonzales and Tatiana say in his review ,I think I have the same problem) .Javier Gonzalez , You can say how you solved the situation, From the moment I get only( bad opinion ) from Blockchain company??? I sent numerous emails to the customer service and they tell me:we don't have information on how your wallet got compromised and now just bad opinion ,,sorry for this" and we do not have an amiable solution for you.... .(I have sent print screen with all crypto transfer,address from my blockchain wallet account and see clearly).I wanted to invest on this platform and I thought it was trustworthy but is the bad experience on my life and I am waiting for an answer from the owner or another high-level function and in this regard and I will prepare many statements to all authorities competent ...If this problem not solved ....I will do a lot of reviews (what I started to do) in this regard to all communication channels if I do not get my cryptocurrency back ...I hope to solve this problem in a friendly way because I am an honest man and I do not like being robbed!I I don't want an answer like this what Blockchain is (noncustodial and don't have acces in my account) I see here many many people have the same problem...If you are non-custodial company and the money is stolen so easy I don't think it should this company work anymore because I saw here many people have my situation...sorry I got to say that but this is the truth...
