As a beginner I want to invest in one of the new digital currencies .. But with the abundance of these currencies became a choice is almost impossible .. I want advice from you .. What is the best currency can be invested by $ 1000 ??
You mean that you want to gamble, not invest. Because if you wanted to invest, then you would consider bitcoin, first. Do you own any bitcoin? Do you have any other financial investments? How could anyone tell you how to "invest", if they do not know about your other investments?
On the other hand, if you are just gambling, then I suppose people can suggest to you various ways to gamble. You might be using the wrong term(s) for what you are attempting to accomplish, no?
I agree, most altcoins are shitcoins as we all know (well anyone knows this if you've been here for a while), so Bitcoin exposure is a must for anyone serious about investing.
At the same time, noobs that don't have much money to invest, tend to try to take more aggressive stances, since doing a x100 on your initial investment will only happen very long term now with Bitcoin. This is why so many shitcoins get funding, it preys on the will of noobs to get fast gains, too bad chances are real low. This doesn't mean you should stop looking for some worthwhile projects in the altcoin world, but assume 99% is trash and it's a finding a hidden gem task, which may be that next x100'er. Meanwhile just stick to Bitcoin for slow and steady gains.
