Bitcoin make idea of owning something come true in 2009. And time has not changed this conception. I think the most important things for bitcoin right now is stability, security and brand of first blockchain. I think that longterm investments is not bad idea even right now. But i could be wrong obv.
Every investment has its own risk wether it will be small or a big investment, or in an online investment, and as for me bitcoin ill say a good place to invest money, yes it has risks but its just a small risk i guess.. the prediction in bitcoin coming from a good source is it will pump up this coming days may it week or years but surely it will pump up.
