in my opinion right now is the right time to buy an altcoin and hold it. but you have to buy an altcoin which is promising which is ranked in the top 100 altcoins in coinmarketcap.
yeah right, the current market price conditions are not yet stable and this is a good time to get a big profit in the future by buying a number of promising Altcoins and hold it them in some time until market prices back recover. the first coin target that must be purchased is BTC or ETH because the price is still relatively cheap and down now.
