To me, if you want to hold Ur bitcoins it does require any special skill, the only factor to consider is the market dynamics, i, e, knowing when the market has fallen for you to buy and reselling when it is up as long as your investment are of long term you would definitely make it.
The trading aspect needs proper attention and professionalism so as not to make wrong decisions that will make you loose your money. Me myself I'm looking for who will teach me crypto trading as a whole. I have a friend who doesn't want t to teach me and he is doing well from it.
