Is There a Minimum Amount I Should Invest?
You should always only invest money that you can afford to lose. The cryptocurrency markets are very volatile, and have seen significant gains and losses within a day in the past.
You can follow the principle of “dollar-averaging” into the market by buying some of the cryptocurrency you are interested in at set intervals. For example, you may be interested to buy ether (Ethereum): You can buy ether once a month, let’s say on payday. That way, you will be able to slowly accumulate ethers at various price points over time in a more controlled fashion.
