If you can't make a profit with a small amount of money, then you won't make a big profit with a lot of money. In the case of cryptocurrency trading, it all comes down to patience, being able to buy low, waiting several weeks until there is at least a decent increase and then selling if there is a strong bullish trend reversal indicator. This is a market where people who HODL can make long-term profits, and you see, it is more advantageous to be a long-term investor than a short-term trader.
And there is no choice than starting with a small amount of money should be use in the process because when you start small you will be able to actually go a long way if you can manage small amount of money, infact people should start with a demo account and this is like the easiest way for them to actually learn better and not burn cash because when you are learning or even practicing you will waste a lot of money.
And when you are starting with actually money you start small and that way you will be able to gain more experience and when you exactly the amount to use and the more you trade the more you actually gain more experience you won't have a choice than to have patience because that is what everyone that love trading do because they want to grow and growth comes with a lot of responsibility. And even holding is not that easy because you still have to also wait for a very long time.
