I know many will say the time ended, we must have bought before 15 days but I think this is the best time. Before couple of weeks ago, BTC was around $4k and which is why altcoins are overpriced in term of BTC. Now that BTC has gained price, altcoins price has decreased in term of BTC and now is the best time to pick your favorite altcoin because right after the BTC ride, altcoin will also follow the trend.
well if the current situation like that I would buy some altcoins that I would use for investment now because seeing a good market makes me excited to invest slowly if I am greedy I certainly spend my money to buy altcoins but that is not what I do because I want to buy an altcoin that will potentially be good later.
