According to Marion Laboure, an analyst at Deutsche Bank Research, the oldest cryptocurrency has what it takes to become the gold of the 21st century. At the moment, however, the transactions are taking too long and the fees are too high. In El Salvador, on the other hand, Bitcoin is used as a payment system via Lightning Network, which is not limited by the block size limit. As a result, transaction fees are much lower and can be processed almost immediately.
However, Marion Laboure also stresses that bitcoin will remain ultra-volatile in the long run, as the value of bitcoin, for example, depends on what people value.
