How can I absolutely make money in the virtual currency?

In the world of investment, there is a method of arbitrage trading from long ago.

It is done in Japan from the Edo period.

In the Edo period the exchange ratio between gold and silver was exchanged at a ratio of approximately 1: 5.

In Europe the ratio of gold to silver was different 1: 15.

In such a case you can easily make a profit only by coming back and forth between Japan and Europe.

I will exchange 5 kg of silver in Japan for 1 kg of gold.

I will bring 1 kg of gold to Europe.

I will exchange 1 kg of gold for 15 kg of silver.

I will bring 15 kg of silver to Japan.

I will exchange 15 kg of silver for 3 kg of gold in Japan.

In the case of different market prices,
You can make money by just carrying gold and silver.

However, as a disadvantage of this approach, time efficiency and monetary efficiency are bad.

There are times when everyone else executes this method, it becomes impossible to use immediately.

While arbitrage transactions can be securely made,
There are also disadvantages.

In modern times even FX and virtual currency etc
Arbitrage transactions are paying attention.
