Hello, since I still grief over mine I am interested to hear yours. A lot more than half a decade back I had 420 Bitcoins, out of fun when I heard of it I started mining and bought some (like, really cheap, less than a dollar for 10 Bitcoins cheap). It was only for fun and giggles, as you might notice, and I never got into it at that time. A "wallet" was for me something I downloaded out of a guide but was not used to it nor used it, really. It was just...there. After I lost my phone I honestly didn't care for the couple of bucks, combined with my none-knowledge about wallets (I didn't even know where the wallet was from, which service or how to login besides the safed login credentials on said lost phone) so I dropped that deal.
After many years, I think in 2017 it was, or so, when Bitcoin shot up like crazy, it was like a different thing for me, I spoke about it interested and checked prices daily even though I didn't have any, until one night where reality hit me that I HAD Bitcoins, I had Bitcoins that cost me around 50€ (overall, including but prices but mostly electricity) that was now worth 420*15.000k€.
Before you say how can someone be so stupid and not remember it, back then Bitcoin was not all around somewhere online, it barely existed, once in months appeared in a news article. For me it wasn't Bitcoin that many years ago, it was a fun thing online.
Long story short: I was never able to recover said wallet, until today I don't know where I set it up, tried to check my mails, but they only go back certain amount of years and I actually believe I created it on a mail account I haven't used for a ton of years since I switched to gmail.

The new development was demonstrated at the Black Hat event. As noted by senior security engineer at Kudelski and one of the developers of the project Nils Amiet, working with the blockchain involves solving various technical problems. With the help of game tasks, the company wants to teach developers the difficulties they may face when working with the blockchain.
According to co-founder and CEO of cybersecurity Trail of Bits, Dan Guido, FumbleChain similar to games, competitions, hacking, used in traditional software development for finding vulnerabilities.
Users accumulate Fumblecoin game points every time they find and exploit a vulnerability in the FumbleChain blockchain. Amier notes that the basic FumbleChain technology is "very similar to Bitcoin," but more simple. Operating Director of cybersecurity company CertiK Daryl HoK said that FumbleChain is designed to make blockchain available to engineers from different fields.
The head of research at cyber security Kudelski in Nathan Hamiel hopes that FumbleChain will find your own life now that his open source code was posted on GitHub.
The lessons of the blockchain
FumbleChain was created after Kudelski completed a number of security checks for cryptocurrency projects, including Monero and Zcash, Hamiel Said. The first task in FumbleChain simulates a so-called replay attack, where duplicate transactions are generated in two separate chains.
Other vectors of attacks in FumbleChain, include validation of input transactions, the discrepancy of the addresses public key and the wallet as well as DoS attacks. FumbleChain also offers a web wallet and blockchain browser that you can experiment with. Later in FumbleChain plan to include objectives for smart contracts and blockchains privacy.
Mark laliberté, senior security analyst at WatchGuard Technologies, notes that FumbleChain can have an impact on existing applications, creating opportunities for "hands-on" learning.
