Its a strange game we all play, as you said 4X returns is amazing but here in crypto land sometimes it just isn't enough. We read the X coin can reax XXX dollar and we hold while fearing a correction/dip. If we sell and the price rises we curse ourselves... if we hold and the price drops ... we curse ourselves. If we sell and the coin dips enough we pat ourselves on the back for making the correct move and then potentially rebuy back in.
It is best to make a long term plan and take one step away from the day to day movements... it is enough to drive one mad.
