Hi,
after bitcoin what are other 5 top crypto currencies in the market ?
Coinmarket and coingecko are the best judge to your question this is to avoid hyping and pumping from other crypto currency,some will say this and that but if you check that on coinmarketcap and coingecko,they are nowhere on the top 50 ..
I agree as I always check the coin status there especially the coinmarketcap. You can check also the volume traded. Those top coins are quite stable to invest and having hundred of millions of market capitalization.
