Which is more profitable, trading in Bitcoin/Altcoins or trading in stock market?? I have some bitter experience trading in stock market, and I am some what new to this Crypto trading, so please share your thoughts.

It really depends on what amounts you invest and what you are investing in. Some people like to invest in the futures market as well. That is faster returns than normal stock markets. Now small coins sometimes make huge gains so it depends on your level of appetite in the investments world.
