Most times it is difficult to decide. But personally I have chosen ETH, XLM, XRP and NEO to add to BTC as my investments and I am confident that those will give me something reasonable within the next few months. But there are other altcoins that are not yet in CMC but doing wonders too. But they are too dicey though.
Totally agree with you. Because I have a similar set of altcoins in my portfolio. But I would also advise buying Litecoin and EOS. Very promising coins.
it is indeed the best coin in investment because besides having the potential to rise high they are also very competent so investors are not afraid of falling in value.
but must focus more on BTC because if BTC rises first then you get profits quickly and can add your capital to other coins.
In any case, part of the savings should be kept in BTC and stablecoins, with their help, when sagging in the market, you can average your portfolio.
