bitcoin are so much expensive now , and litecoin are so much cheaper people start accepting them as well
And this will have a knock on-effect. Once BTC price gets ridiculous - maybe it already has - people will just invest in the next biggest currency; Litecoin. Then when Litecoins get too pricey; on to the next and so on.
Nope, by your logic, smarter would be start with new and still worthless alternative coin.
Litecoin is already too much expensive + useless
The line of reasoning in this subthread makes no sense at all. 1 Bitcoin and 1 Litecoin are arbitrary units. If they is expensive to buy, then you can buy more with them as well. If you think bitcoins are too expensive, then change the settings for your wallet to millibits or microbits. If you are hoarding coins, rather than usng them to buy things, it doesn't necessarily follow that a coin with lower price will increase in value more in the future. The network effect is what makes coins valuable, and it makes no difference what units you use to define them. After all, 1 kilolitecoin is much more expensive than 1 bitcoin.
