Between Litecoin and Dodge as a replacement for BItcoin if BItcoin runs into trouble, I would pick Doge. The reason Doge has a tail emission. The biggest challenge facing Bitcoin today is the 1 MB blocksize limit. What many do not realize is that the reason why there is so much division among the Bitcoin developers is that there is no simple solution to this problem. Simply increasing the blocksize only kicks the can down the road. The issue is how do you secure Bitcoin once the block subsidy runs out? This is why many are so reluctant to increase the blocksize in order to make the blocksize a scarce commodity to ensure that there are enough transaction fees to secure the network.
We are paying 3600 BTC a day to secure this network. Paying the miners 25 BTC every ten minutes.
Compare with Bitcoin Number Of transactions Per Day:

(picking a best case scenario, on a day with merely 1 transaction the numbers are staggering)
On the same day we had 466 USD / BTC on Bitstamp, so 3600 * 466 = 1.677.600 USD to be paid for 227.000 transactions processed.
1.677.600 USD / 227.000 transactions = 7.39 USD and I tend to believe that seven dollars is enough postage payable for a single "Bitstamp" why heading for an even more expensive transaction fee? I cannot afford to pay seven dollars postage and packaging when sending a single dollar to somebody.
