If you're doing anything other then pump and dump on coins with the potential, like GLOBE and START, then you are just wasting your time and money. Alt coins arnt even an asset, unlike Bitcoin which is an asset and is traded on the general market and can be shorted against actual currencies.
My advice is look at the charts for each Alt coin. If you see any with drastic repetitive spikes and drops, buy at a low and sell at a high, then transfer back to BTC. If you're in the US, hold USD until the buy is capable, transfer to BTC, transfer to ALT, then at the spike sell off back to USD. Otherwise your Altcoin value is volatile by BTC price drops. If you're hoping to invest in LTC and take the cake if BTC price plumets, well I don't see how you're coming out of top since all ALT coins are pegged in the market to BTC anyhow. Your order of value and investing in ALT coins should be looked at in terms of, what is the currency value which is pegged to BTC, what is the value of the ALT coin pegged to BTC. If you did like me and invested in START before Max Keisers 48 hour STARTcoin fund on BankToTheFuture when START was like 0.00012 and BTC was like $235, then you did pretty good a week or two ago if you sold when START reached 0.0008 and BTC was up at about $300.
Read the news, watch the charts, don't marry your investment.
