Definitely. It's really luck nowadays to get a good investment or trade that's why you can opt to take the trading for those with good charts or maybe the ones that are there with good products and support.
skills and knowledge are both important aside from luck in order to become good at investing because nowadays there are indeed lots of scams whether it is from ico or on bounties and airdrops.
sticking to some trusted and popular coins would also lessen the risk of being scammed because your are already sure that your invested capital wont be wasted plus it can also get a return if you are only investing on some legit coins like bitcoin and etherium.
