Interests

Bitcoin and Crypto Currencies

Since 2013 I have started to be involved in the Bitcoin and Cryptocurrencies world at the moment that Bitcoin mining started to decline and Scrypt mining had started with Litecoins. I have developed deep knowledge about this field and I am a strong believer that within a couple of years the current monetary system will be completely replaced with a new monetary system which will be based on Digital Currencies.

IMHO however Bitcoin and Cryptcocurrencies are not that digital system yet. It was inplemented to achieve distributed consensus and anonimity but has big disadvantages which makes it unsuitable for business systems in its present form. The bitcoin blockchain is slow and expensive and misses essential business transaction information. A new system needs to be developed that could be based on distributed database technology.

"The internet is going to be one of the major forces for reducing the role of government. The one thing missing, soon to be developed, is a reliable e-cash."
