I suggest to buy ethereum why , as we've seen ethereum is growing too and still increasing , but maybe the half of your 1000 dollar invest it to ethereum the other half is try to different altcoins such as litecoins like that. And the half of it I think try the method of buy low and sell high process to have a extra profits or to have a great income. The ethereum is still growing at the same time , but I suggest too that search it or even surf to a different sites, but still beware sometimes it can lead to scam sites okay? Be careful and awareness , and be wise.
