if you have no trading skills it will be a waste of your time and money. there is nothing wrong if you want to earn money from trading, but you have to start by learning some techniques and also how to choose trading assets. if not your small capital will just disappear without you feeling any advantage.
maybe if you are interested in investing, you can buy Bitcoins consistently with your $ 20 in a certain time interval. so you can have quite a lot of Bitcoin when you are strong enough to hold the asset.
Uh no? I have like the similar starting money like the OP's but I still learned a skill back when I day traded. Just by learning by theory and reading around the resources in the internet would not lead you so far in your learning experience, you would still need to apply those skills into practice. Let's say I watched Youtube videos from CryptoJack back in the days and I followed the trading tools used like RSI and Bollinger Band. I invested like $20 to those just like the OP to learn.
The bottomline is that it is perfectly fine to start with $20 to learn trading and it ain't no wasting time unless you really just go straight up. I would do it over just virtual trading where I would not feel any shit if I encountered losses to that.
It is wasting time and your health, life happiness too.
With only $20, you will lose a lot in trading fee (if the exchange you use for trading does not give user 0% trading fee). Trading is stressful and if you are newbie, you will spend lot of time to watch the computer screen, chart and it costs your time. Spending too much time on your chair, with your computer will make you more sedentary which is bad for your health.
With $20, let's buy a coin and hold it till it becomes bigger. In addition, you can use your salary and saving (part of it) to accumulate more bitcoins.
You got a point, but if it is for learning trading, it is not. If I have not tried day trading before, I might be curious for the rest of my life on how does it feel to watch my computer screen for almost 8 hours continuously while trying to earn.
I did stop trading since it is not for me and for my work habits. Trading is still stressful even for experienced and veterans considering the market is volatile.
