hi , is anyone available to send to my wallet 1-2-3$ worth of LTC and I will send you the money via revolut (in whatever currency you use)? buying directly such small amount generates very high fees .
Since you are a newbie, no one will venture to send you a penny regardless of how tiny is the amount you ask for. You have to be ready to send to send payment first (trust a strange) or use an escrow agent which is also a dumb idea because of the small amount. My suggestion for you is to contact one of the trusted sellers and send him few dollars in fiat to recieve LTC.
By the way, why do you need 1,2,3$ in LTC? Are you trying to test something with LTC? You can explain further because there are already a testnet network for Litecoin which is dedicated for development experiments and educational purposes. You can get some LTC testcoins from one of the available faucets, or just ask anybody to send you some for free. Blockchain for LTC testnet:
