The virtual currency around bitcoin is bubbling again.

On Tuesday, up to 69,369 bitcoins were transferred from one Bitcoin wallet to another unknown Bitcoin wallet.

At the time of the transfer, the value of the bitcoins was approximately EUR 833 million.

According to Ars Technica, which compiles the events, the wallet has not been used since 2015.

Tom Robinson, co-founder of Elliptic, a company that researches blockchains related to virtual currencies, believes bitcoins come from the huge Silk Road online store that closed in 2013.

Among other things, drugs and assassinations were traded there.

Robinson estimates the wallet was the fourth largest in the world.

The transferor of the bitcoins is not known, but it may be someone involved in the operation of Silk Road.

There are also allegations that the wallet in question was traded in the underworld and that someone would now have managed to break into the wallet.

However, the chances of skipping the wallet password are considered low.

A Bitcoin transfer of the same size in euros was also made a year ago.

In this separate transfer, which concerned a completely second wallet, the value of the bitcoins reached EUR 923 million.

There was no certainty about the transferor, but according to some theories, there may have been some Bitcoin exchange or individual behind it.

Usually, the best time to identify is when and when you try to convert bitcoins to a traditional currency.

This has also been seen as one spark of hope to catch the Vastamo tightener.
