Yes, the profits might not be felt if we invest lower amounts. Investing into cryptocurrencies can be a way more profitable from stocks and if we invest at the correct time in the correct coin then for sure we can have a lot of profits out of trading with the cryptos. Investing small amount would also not meet the minimum requirements on the exchanges to exchange your coin into.

There are certain limits on your trade and I am sure on one would like to be restricted on the time of making the final trade or withdraw just because of lacking some satoshi's for the minimum order. A lot of precaution needs to be taken before investing smaller amounts like this.
