I have heard quite a few things about Arbitrum but not that much to make me fuss over it. Even my friends haven't mentioned it but seeing all the positive things here about Arbitrum, I am considering reading about it more. If all goes well I might consider jumping into this ride as well and may even share it to my friends. Does anyone know a good competitor for Arbitrum or it doesn't have one at the moment? Would want to take a look at that as well if ever.
How informed is your friend about the cryptocurrency market, because if he was informed them he would had mentioned Arbitrum to you because it's all over the cryptocurrency news, it's the hottest project in town.
Arbitrum has so many good competitor and the most popular and already successful is polygon. If you aren't aware, Arbitrum is a layer 2; blockchain that helps fasten the transaction happening on ethereum blockchain.
We have so many layer 2 blockchain and they all became popular after the success of polygon so you shouldn't waste time if you want to invest in Arbitrum before it starts pumping, it's already listed on Binance.
