In seeking the right exchange, interested parties must first know what they are seeking to achieve. For example, is the goal simply to invest for the longer term, or to trade cryptosystems with and from positions on a regular basis?
Investors might look for spot exchanges. These are platforms where you can buy and sell real digital assets yourself. Spot Bitcoin (BTC), for example, is real Bitcoin that a person can buy, sell or transfer to any exchange or wallet at will and hold for as long as they want.
