I do not agree with the thread poster, i still think that btc is the best long term investment, atleast when we compare it with bch, there is uncertainity about bch in the market so i think holding btc is still better, it is gonna be extremely profitable soon.
I think if the situation is like this and the market price is very low this is the time that you must hold your bitcoin, because although if you sell your bitcoin for now you didn't earn profit so better if you hold your bitcoin for now. Holding is better if the market price is very low.
