Will Litecoin pass 10$ by the end of June?
I dont believe it will. Doesnt seem to have enough demand tbh. Maybe if a few auctions sites like a certain infmaous one took LTC it would pick up, but well see.
If you mean eBay, it'll never happen. eBay owns PayPal and PayPal has said many times that they are against BTC (cryptos in general). I think it's because it's an alternative to their service and they don't rack up tons of fees by having a near-monopoly.
