In my opinion, analyse the market for at least a month how the market behaves before starting trading. If you enter the market without knowing much then you are taking the chance just like gambling.
Right, it is not good to start trading when you are not sure what is your plan, as there are so many ways to gain knowledge and then you can trade safely for long term, it is own experience when I bought some coin without having knowledge only because my friend asked me to buy then I end up losing my profit but after being experienced I recovered my lose and I am earning high amount of profit.
