Cryptocurrencies are not the same as regular currencies in many ways. There are few main specifics that are important to consider when you’re working with cryptocurrencies - before you make any technical decisions.
The cryptocurrencies don’t have cents, but they have the decimal part. It’s a common approach to use Satoshi units (similar approach to having amounts in cents, as integers) in order to guarantee the precision. Below you can find the unit translation table between Satoshi units and BTC:
Cryptocurrency conversion rates are very dynamic. For instance, BTC or Ethereum equivalents in USD are both known for their high equivalent value. Thus, the fiat equivalent of transaction amount may often indicate a 2-5% difference between the USD amount at the moment of transaction start and the moment when the confirmation is received.
Fiat is mostly static, it does not happen every year that a new fiat currency is introduced or existing one disappears. On the other hand, crypto (usually) does not belong to any government, it may be registered by individuals, the procedure requires quite a few steps to be created. This characteristic determines the nature of cryptocurrency - currencies are often added on the market, or removed. Make sure to stay on top of the offerings, and stay tolerant to new currencies being introduced, unless you are confident about a specific list of cryptocurrencies that you want to work with.
