I don't want to put my money on unfamiliar coins, so I always do invest on the top coins. Today, if you have some spare money better to buy ETH and XRP because the pump will begin again and you will earn more if you do it. The future is still good for the altcoins, they will move like bitcoin.
Right now, when the bear market has been around for long, those coins have disappeared and for a risk less and safer investment, the top coins particularly Bitcoin, ETH and ripple are preferred over the rest of the coins. Hence, if you want to have good secure future in BTC or ETH, stick here.
