So if you have 1BTC now, what coin or coins you will invest your 1BTC? Will you invest it to a single altcoin?
In my case I'll invest it to my 5 favorite coins equally.
$STRAT, $ETC, $SYS, $DCR, $TIME
How about you?
Investing in a single coin is never recommended. You may loose it all if the coin fails. Also the trend shows that less than 1% of newly launched coins are actually successful. You may study the market trend of few coins and then decide accordingly. However, I would not invest my bitcoin in any other coins, because bitcoin has a huge upside potential than any other coins present in the market.
Also I would invest a major percentage of that amount in trading with currency like BTC Vs USD or EUR. Trading is the only method which can give you a good return if you know how to play in trading.
