Trading is not a simple skill to master because of the risks involved, which must be taken repeatedly before you can be successful. If you said Trading will be your focus this years, you need to be learning much about it and know the strategic how you will be staking, and you need to know is better you trade with the money you can afford to lose, because Trading is not an investment that you will say he can minimize your risk when you start, I would like you to not focus on one aspect instead, you should be investing so that he can increase your knowledge about different coins. As for me, I believe in investing more than trading because I haven't gained much knowledge about it yet, and I can't say if I start trading I will be profitable, because it is very risky more then investment but if you are lucky you will profitable and change your lifestyle.
It is indeed not an easy thing to be able to master trading well, we need to study it well to be able to really master it well and even those who can already trade are still learning about trading so that they can trade correctly, in doing so. In trading, of course we have to use capital that we can afford to lose if we make mistakes in the trading we do.
I agree with what you say, of course it would be better if we could trade and also invest and when we get a profit from the trading we do then we can invest to be able to get a profit from both of these things. If we don't have a good understanding of trading, it would be better for us to invest first in order to minimize the losses we will incur and when we want to trade, we can learn it first because it is very risky to trade with only a little understanding of trading.
