LightDoge is very fast but not supported by a lot of exchange.
LightDoge is not an altcoin that you see on many exchanges, Dogecoin however is listed on almost all of them and the confirmations are fast. and also as the other posted said litecoin is also fast enough and has a low fee.
also keep in mind that being fast is not the only factor you should look at. you should also check to see
how many confirmation the exchanges need. if they need 3 confirmation for bitcoin they may need 120 confirmation for another altcoin which can take a very long time, even 2 hours to reach that much and that is if you are lucky and don't fall in a difficulty retarget period which takes longer.
Bitcoin is awfull, usually takes 1h to 1h30 for my money to be transferred.
What other crypto out there is fast?
this is wrong, because if you withdraw bitcoin from an exchange, unlike you the exchanges pay a high enough fee to get a high priority and that means their transactions will be included in the next block which on average will take 10 minutes.
i heard eth je faast
it is fast but not the fastest and certainly not the cheapest either. the fees are very high!
also you have to at least transfer 0.1 ether to another exchange otherwise they will accept it as donation!!!
