I heard people mention oyster pearl (PRL) and BAT quite often but I have no idea if it's worth to invest in one of them yet. There is so much choice in the Altcoin market... One thing that is sure in the case of BAT is that the team is very good.
The team is one of the best out there for sure. And right now, with all the bleeding from the market, I think it's the perfect time to put some money into this coin. There's a ton out there, but most of them are pumped up with nothing backing them up. This coin actually has a working browser and their road map looks great.
