Hi guys, the last hours the Bitcoin , Ethereum, Litecoin and most of cryptocoins fall over 10%.

But why ???

Because a report from BitMex research reported that a critical flaw which is named "Double spend" had happened in the Blockchain technology.

What it is Double spend ?

When a user can spend the same amount of Bitcoin multiple times.

Here you can see the tweet https://twitter.com/BitMEXResearch/status/1351856488252399618

It appears as if a small double spend of around 0.00062063 BTC ($21) was detected

So we will see the next days what it will happen.
