Yes It is still possible but it is very risky and also very difficult nowadays. there are too many exchanges and also prices are well maintained and almost same everywhere. you'll hardley find any chance.
You need to be super active in many exchanges, and watch multiple assets to find the right opportunity.
then doing KYC in so many exchanges ia nother problem. withdrawing and depositing take different times in different exchanges. you could miss a lot of chances because of that. and also you need a huge capital for that. I don't think it can be done with small investment. you would need around 1 BTC.
