Although it looks promising, bitcoin still needs to face the challenge of being called a fully digital currency.

Some skeptics say token fundraising has the potential to turn into a bogus investment if not regulated. However, tokens make it easier for companies to earn money faster than other companies. Likewise with startups who do not need to depend on their advertisement to provide services to their users.

In addition, bitcoin is also often used by hackers who spread ransomware. The anonymous nature of Bitcoin makes it easier for hackers to get money from their victims, as in the case of WannaCry some time ago. Without the need for a bank account, the criminals will get money.
