1. invest it in 1 altcoin (short term/long term)
2. putting your eggs in different baskets
which means i will divide my 0.004 and buy at least 3 alt coin (short term/long term)
For most altcoins; there is no such long-term, but for some potential coins such as eth, xmr, ltc, qtum, bytes, waves, yes you can hold it for few months or years and get higher profits.
Divide your investment into different coins will works if you have big capital.
It's better to invest in a potential coin such as iota, ripple or xlm, these coins are on pumping right now, but I'm sure xrp can rise at least to $5 and maybe $10 at the peak.
