  • Theoretically cryptocurrencies are interesting, but Bitcoin just isn’t usable.

    Bitcoin and many other currencies have way too many and large fluctuations in value for daily use.
    Bitcoin specifically is not practical for transactions in general due to cost and block size limits. Yes, lightning exists, but maybe your technology is shit if it needs a second overlay network to function.
    Instead of fixing those issues, most other coins are just pump and dump schemes for a quick buck.
    Only very few coins try to do something different and fix some of these issues.






  • Open UDP ports are pretty secure and rarely found by scanners. The basic issue with scanning for UDP is, that most services don’t respond to random garbage you try to probe then with. Without getting a response back, the scanner has no way of knowing if there is something running on that port or not.
    Wireguard in particular only responds if the correct key is given.
    Also make sure your firewall DROPs (usually the default, but do check) disallowed connections instead of REJECT. This way any UDP probing, whether it’s to an open port or closed one just times out with no way for the scanner to distinguish them.
