My favourite altcoin right now is Litecoin. Although it's an old coin that not many people are talking about these days. But at the beginning of August, LTC will be a halving. I expect that before that time there might be a pump, if nothing negative happens in the market. Halving is a fundamental event that always affects the value of the coin.
It's not being talked about because it's an underrated coin but good for transfers. I'm not expecting a lot from its halving because I saw the past of its halving and observed if there could be some changes but not that much really happened after all.
So, if you're expecting that there could be some pumps with it. I don't think that you should be expecting a lot from it but then, it's your time to observe and maybe there will be a new observation that will come out from the moment you take a look at it.
Other than that, if there will be some coins that many will pick, I'm sure that there's high confidence in Litecoin because it's known as silver while bitcoin is gold.
