Hi,

i would to know, what are the main importatnt alternative cryptocurrency to bitcoin??? example: litecoin, megacoin.....

- Why these kind of coin have need to exist? because bitcoin have some problem, or issue, and this type of coin are born to resolve this issue, or for another mission?

- this other coin can work with the same process of bitcoin (blockchain, private and pubblic key, process of mining??)

- the alternative cryptocurrecy can be considered a true alternative of bitcoin or these are weak to challege bitcoin??

Thanks

Hi.

Your questions are very debatable and this can simply start a flame war.
Best alt-coin? Hard to tell. Some are old, some have big fan base, some are anonymous. Some are bitcoin clones (with few or with big changes), some are built from scratch.
Some have big advertising (cough Dark/Dash cough..), some ... need more checking to be discovered. You'll have to do your own detective work and see which altcoins deserve your attention.

About problems: some claim anonymity and it's not sure that they actually provide it. Some can be mined by ASICs, some with GPU, some only CPU. Some are PoS (you only keep wallet open, no big resources for mining). Some are cheap IPO/ICO scame.

Afaik have blockchain, but for some you will not see that much info like for Bitcoin (like top100 richest wallets and the amounts in them). Mining can be done with hard work (PoW), only wallet open (PoS), by providing HDD space, ... maybe some others I don't know.

Some anonymous coins have a tough fight trying to be the anon alternative to bitcoin. Some just use TOR, some are college clones, some are just scam. Some are dead coins.

I will just tell the altcoins I like, for various reasons: XMR, DOGE, FIBRE, XMG. I will not tell that they are best. Time will tell if my choices were any good.

Good luck in your search!

There isn't "important" altcoin but there are "most used" altcoins. Litecoin, Dogecoin, NXT are some of them.

Some coins came with a few features which Bitcoin doesn't have. But most coins came into existence to scam people.

As They are coins made cryptographically, they work almost same. However, there are different algorithms for different coins. Private key and public key works similarly but coins using different algorithms, private keys and public keys will be(look) different. They are various way how a coin is minted. Bitcoin uses POW for it but other coins uses POW, POS etc...

Altcoins aren't a "challenge" to Bitcoin at any means.
