This is the reality when it comes to altcoins. There’s no such thing as a perfect altcoin to buy right now, because every single one of them are subjected to substantial risks. However, if you want something long term other than BTC, your best bet would be ETH. If you can afford to set aside a small percentage of your monthly income into ETH (a.k.a. Dollar-Cost Averaging) no matter where the price goes, this is going to potentially build your wealth on a consistent basis.
