Good long term investing are gold or real estate because you have low chances to loose your initial capital amount. Bitcoin is good for speculations.
Gold may cost $500, $1000 or $10000.
Bitcoin may cost $500 or $10000 too but it can be $10 also.
the probability that bitcoin will drop to $10 is very low right now. The halving is coming! the hype for buying bitcoin will increase gradually. long term investment will always be good. If you want gold or real estate than why you are here? (although you maybe right)
