Did any one of you lose money buying Bitcoin?
If yes, Did you again reinvest in Bitcoin after losing?
If yes, What need you reinvest your money on Bitcoin?
I lost money after buying cheap coins like BCD, ACT, and Abyss. Yes, I then decided to re-invest in Bitcoin. Bitcoin dominates the market and I see the price is rapidly changing. It's time to regain profit and I think, I prefer to buy Bitcoin.
Do not give up the because if you lose, one time you will definitely feel the victory again.
Ever thought about other Alts, but more popular ones, eg Top 20 ones? Maybe try to diversify a bit, there's big gains there too.
