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.
Not much only $500 I can invest now and I can hold it for 2/3 years. If I don't have much money then I will not invest in Bitcoin? I'm not clear.
