What was the value that you bought/sent ETH/open.ETH? And did you use the platform during that period to get notifications?
Initially I sent 0.231562 ETH to the BitShares wallet, I bought 283 BTS and the rest of my money I left in Open.ETH up to now. I made this investment 29.01.2018 (see the screenshot), and the price of ETH at that time was about ~1000$ ( https://coinmarketcap.com/currencies/ethereum/ ). Then the prices went down and I left my investments for better times. Recently I decided to check how much I earned during 3 years and surprisingly I discovered that my money were actually stolen. I never received notifications neither from BitShares, nor from OpenLedger.
