Each asset holds a value, often priced in U.S. dollars, which leads to another use case: trading and investing. Aside from stablecoins — which seek to stabilize the instability of cryptocurrencies by pegging an asset to something else, such as the U.S. dollar — most cryptocurrencies constantly fluctuate in price. You can trade between cryptocurrencies and national currencies (called fiat currencies) on exchanges, depending on the trading pairs available on the platform of choice.
Cryptocurrencies either have a limited or predetermined coin supply—although, with over 2,500 cryptos listed on hundreds of online exchanges, a number which is sure to increase over the coming years, it’s hard to generalise.

Yet some crypto watchers have raised red flags over SafeMoon’s unusual structure. It charges a 10% fee to buy tokens and another 10% to sell -- almost unheard of in the digital currency world. Half of these fees are paid to owners as an incentive to keep holding and the other half goes into a liquidity pool controlled by the developers. SafeMoon calls itself a DeFi token, or one that uses decentralized finance to govern functions through software, but it has a chief executive officer and chief operating officer. Critics also worry about the discretionary nature of the “manual” coin burns used to adjust its circulation.
Just like you shouldn’t let a price drop influence your decision to buy crypto, don’t let a sudden price increase alter your long-term investment strategy. Even more importantly, don’t start buying more crypto just because the price is rising. Always make sure your financial bases are covered — from your retirement accounts to emergency savings — before putting any extra cash into a speculative asset like Bitcoin.
