I have a knack for trading so I am a number 3, but I am a number 4 in that I leave a percentage (relative to how much confidence I have in a particular coin at the time)
At the moment I hold 55% ETH (I believe in the dev's) 40% in BTC (I have no next to no faith in dev's but faith in china and india once bubbles start to pop) and
5 % in steemit because I am going againt my fathers advice (if it sounds too good to be true, it probably is)
