I am no shill for free-wallet nor do I claim to know anything about their legitimacy but I did use minergate a few years back and that did end up with me using freewallet.org app on my phone for the transactions on minergate for mining rewards.
Even if your account is in good standing with Freewallet you must consider all those people they scammed, freewallet is a scam exchange no need to defend it even if they have not yet scam you but you will become a target soon, scammers are a scammers they have a criminal mind just check the so many scam accusations, no way they can regain their reputation.
agreed - I am in no way defending them - only sharing my experience. I count myself lucky to not have lost anything.
