It is not a speculative coin.
They buy it and keep it for years, for a lot of growth.
If you can spend a lot of money and wait so much, then it will be a good investment.
If not, either forget about it, or try to trade on cheap coins.
And for this you need to be able to read graphics.
the OP didnt clarify whats he wanted the investment go,either long term or short term or maybe daytrading?but i guess since he had mentioned bitcoin is he know it was great for long term holding.
If you can stand holding coins for 2-3 years so go buy bitcoin because this is what we do for our investment.we are willing to wait for long just to profit good.and to be ready for our future
