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.
See you have to find the potential coin before investing beacuse I never wait for more than a year because there is a possible chance that the price can increase below one year only but you need to divert your money to other best ones also in order to make more profit on the investment you made.
