Engaging in crypto doesn't guarantee that you'll become financially stable or wealthy. Because not all traders are able to gain when they trade even they're long been here and used to the market movement and knowledgeable on how to make an analysis. That's why many of us don't go full time because we can't only rely on trading (though there are traders who managed to do so) and it's wise to have another resources where we can earn a stable income.
Anyway, trading/investing are profitable but it can't make you wealthy using a small capital and in a short period. Hence, be aware of the facts before trying to engage yourself to avoid having disappointment.
This is a misconception which is very common, newbies seem to believe that just because they become part of this market riches will come their way and nothing could be further from the truth.
In order for anyone to make profits they need someone else to lose, this means that if we buy bitcoin there is someone else out there which believes bitcoin will go down soon and this is what makes them willing to sell, the trader which can take the correct decision the most often is the one which becomes a long term winner, and it is unlikely a newbie has the necessary skills to compete against traders which have been here for years and will end up losing their coins to them.
