I would recommend you put a small portion of your btc holdings into new altcoins that have potential. it is common for new altcoins to multiply their initial value very quickly. Just look at ripple. it went up 100x in just a month.
And it comes down to 1 or 2 sats in no time . Be very careful when investing in new altcoins .
I would say investing in Doge and Ldoge + RDD is the best option right now.
Not the coin that I expect to be recommended for investment. Its usually Ripple and NEM that I've heard of these days but doge? RDD? These coins have been around for years already and never got the chance to fly low. I ca't remember when its price reach up to $0.01.
I would recommend ICN instead.
Just look at CLAM, XRP and XMR, those coin will actively pumping and i can able to get high profit for this coins, but just invest the amount that you can afford to lose. But you need to have more time to monitor that movement in an exchange to make you much higher profit, do it regularly.
I agree that many of these altcoin are good to invest money in. Their volatility is profitable and one can make good profits off their prices if they can time themselves right. But its true that not everyone can monitor the markets all day and hence they cant make such trades. Long term holding might be good for them - but in that case bitcoin is a more safer option than altcoins.
