For investment, I dare directly answer Bitcoin and Ethereum. However, if it is a long-term investment, I do not dare to give a definite answer. I think, Bitcoin (BTC) is one of the few cryptocurrencies that is safe for long term investment. Again, I can't guarantee 100%.
We don't guarantee any kind of altcoins future. We can only predict because we have experience. As OP's list of altcoins, I can't support any exchange tokens without offering us several services like Binance. From yesterday I've been thinking that we need several services, such as Binance. Binance is getting more demanding coins until it has a good competitor.
