The crypto market is highly volatile, which means that you can make massive gains and lose it all within a few hours. However, you can mitigate your risks by learning technical analysis while understanding how the market runs.
Some cryptocurrencies have higher market caps, such as Bitcoin and Ethereum, while others have lower market caps. The chances of losing massively within a short period are slimmer when trading coins with a high market cap. This is as compared to trading those with lower market caps and volumes.
However, you are also more likely to make quick gains from altcoins with lower market volumes than those with higher market volumes. Hence, it is best to choose which one works best for you before opting to trade cryptocurrencies.
