The truth of the matter is no where is safe.. all the coins are just fluctuating due the volatile nature of cryptocurrencies. I will side with you on them going for the top coins due to their only ability to bounce back even if there is a massive dip.
Obviously, in terms of making a profit on a coin, it is better to choose the old coins rather than new coins or coins that are being developed, because the old coins have very strong foundations despite sudden price drops, but are still able to rise all of a sudden too.
