People generally here mention only those coins that they hold in their portfolios and it can not be the hot choice of everyone because every trader/investor has a different perception for buying some trust on an old project or some take the risk to buy the new coins. I heard about only Sand in the last 2-3 days because it was trending on Twitter so I came to know about that. I noticed Mina and Sand has a good no of holders and that's not a bad choice but there are some other high potential coins that have been tested and survived strongly.
