Diversify Investments is a very important thing, never put money on one or two types of investments because we never know with the future of the coin, this certainly makes us have to be vigilant and do not depend on a little coin.
as much as possible youneed to gather more informations regarding the market, and you shouldn't depend on someone's opinion when it comes to how many coins you are going to invest or what are the coins you are going to put your money into. you should also observe here, and as you can notice that lots of them has their own perspective and their own suggestion to what are their top picks for investment, then you try to research about those suggestions and make your own tentative analysis.
True and this is what I was actually doing, although $1k is not that much for investment you can always add your investment over the time. Im sure that is not only the amount of money you can save for investment. And yes you also have to do some research on some alternate coins aside from bitcoin to invest, there are actually a lot of potential coins that are good for investment so always diversify even if you dont have that much money for investment.
