17. Benefits
• Some coins can help you stay anonymous but contrary to popular belief,
not all of them can. Bitcoin is pseudonymous which means people won’t
know exactly who you are on the blockchain but they can get some
information from it.
• You don’t need to share your identity or whereabouts or the details of the
transactions made between you and the beneficiary. No information is
required to share with the government and the bank regarding the deal. It
is truly decentralized.
• When you talk about transactions using cryptocurrencies then there are
no limits. You may be in a different part of the world and the receiver
might be some other hemisphere, you can still transfer the amount
without any hassle.
• Cryptocurrency is readily available to the general public. Almost anyone
can make use of it.

18. Disadvantages
• Cryptocurrencies are relatively new and come with a learning
curve. People end up investing without proper knowledge and
lose money to something they did not learn about.
• Not many websites and companies accept digital currencies
yet. Very few countries have legalized the use of
cryptocurrencies. It makes it impractical for everyday use.
• If you mistakenly pay someone by using cryptocurrency, then
there is no way to get a refund of the amount paid. All you can
do is to ask the person for a refund and if your request is
turned down, then just forget about the money.
• People are not aware of how to use cryptocurrency and hence
open themselves to hacker.
