Thread seems old. but I am excited to explain my view. I think, Both option are good, depending on person and his management skill..for me, due to my busy schedule i always be  priority  to investment rather than trading, even trading always seems risky to me. If you invest top altcoins as well as some valueable worthy altcoins, then will make profit whinin few years as cryptocurrency sector is spreading daily and growing up so fast. As well as you don't need to be worries but trading will always give you a little worries, wrong management can make you face huge loss. Although it depends on what suits you most according to your condition
