Bitcoin is one of the first and most popular crypto-currencies that does not have direct competitors at the moment. However, over the past few years, there have been quite enough crypto-currencies in the market for altcoins offering new platform capabilities and increased security. The more new and convenient solutions are offered by digital currencies, the sharper the need for "oldies" of the market (such as bitcoin) in modernization. Otherwise, the coins simply become obsolete.
Perhaps this happened with bitcoin? In fact, there are many internal and external factors that affect the BTC and can play a role in its fall.
Internal factors include:
transaction fees;
block capacity;
infrastructure.
The idea of internal conflicts and overstated commission was especially zealously promoted by Roger Vero, an adept of Bitcoin Cash. The idea of an unnecessarily high commission and a low degree of protection was picked up by many bitcoins-experts. This could not but affect the perception of BTC investors.
