I realy want to buy altcoin which coin can i buy to hold and make big project in future any idea tell me best profit coin to buy thanks.
if you want to buy coins for the future choose a coin that has a large capitalist and has a rank of 1-10 marketcap because it is a coin that has the potential for the future
that's a good answer but to generalize those coins are sitting below top 10 coinmarketcap is not a good idea. Remember he must take the product as the main thing that can give the result whether that coin is worth to invest or not.
The advantage of the top coin is on its liquidity and demand.
