Actually, its good to buy the dips if you have a strong mind of just filling your bags with some coins to make it look heavy☺ not to quickly dump it once it get a little sharp rise.
This is mostly what majority are doing and its gonna burn your heart.
Only buy a coin to be part of the network rather than buy to be part of the gainers (which in most cases, will end up being the loser because of the tyrant whales in the market before you).
A simple advice.
Buy whatever coin you felt is at the dip now, lock them up, and get your mind off it, do your regukar activities, quit being a full time crypto spy and learn to endure even in the hardest temptation. Always remeber, tomorrow is another day, put on a big smile, and say to yourself, "even if bitcoin is dying, what more should i expect of it when all things gonna die"😉.
PS: bitcoin will hit the lowest mark you can ever believe this year and wont ever rise until mid 2019.
