Guys better to use the ignore button and the site is not safe for us, I believe that he owns this website.
Unless if he can provide a proof that this review is true.
Slightly confused as to whether the OP meant that they originally paid €100 over a year ago to buy the BTC which is now worth €500... or that they paid €100 one year ago to get their wallet unlocked...
The OPs other 2 posts are from January 2017 saying they were unable to restore their Electrum wallet from seed... so maybe it is the second scenario?
It's obvious that the review is not safe. Look at the post that he get the seed from the cloud but when recovering it to electrum wallet he couldn't click the next button it means he choose a wrong option or there are words is wrong spelling.
However, according to his review, he is talking about a password and private keys (Not a seed phrase) So my guess that he is lying and he owns that website, he made an account here to promote his own website and get backlinks here in the forum.
