Right so from my understanding, and from listening to the people on the forum here, you need to read into the coin you want to buy etc.. However so many altcoins just had a pump yesterday, is it even the right time to buy now? And how do you choose an altcoin you want to read in to and possibly buy?
Do you scan coinmarketcap.com? If so, what do you look for?
My personal advice, look at some of the main aspects such as the age of coins, volume 24h & the market cover of the coin itself .. yes even though the movement is very fast.
If the coin want to trade still looks new ,, note how the community activities and total supply coin .. from there we guess what kind of future coins.
