Yes bitcoin is a goodway to invest your money... but now i think the value of bitcoins is raging up maybe if you invest past few years ago maybe you're rich now, or maybe you can invest in some altcoins and maybe it will become a bitcoin or in other word an altcoin that you will rage up the price soon like ethereum. I've read many threads here that ethereum will replace bitcoins but we're not sure about that
It will till depends on the person. Easy money is not a good thing to expect, you have to work for it always and best thing comes when for it. If you can afford the minimum amount of investment will do, and be sure you are guided with someone who has the expertise with his kind of talk and be determined always cause it will you to success
