Limited supply
Verge, its supply is capped, and the limit is 16.5 billion. Not only that, but the large majority of the coins have already been mined. Because of this, the price of XVG has a large potential to jump up, since the demand will increase in time.
This is true of 100 other better coins.
The price is still cheap and the coin is stable
It would be much smarter to invest in it right now, before the market recovers, and Verge reaches the value it had in December 2017. According to the CoinMarketCap, its current price is $0.039104 per coin, which allows for the purchase of a large number of coins at a very low price.
Everything is cheaper than December prices right now. You are also assuming Verge is going to recover.
Privacy and security
The one thing that gives Verge an advantage over many, many other cryptos is its approach to security and privacy of its users. Many coins offer anonymous transactions, which was great at first. The problems appeared when anonymity was misused for criminal activities, which has forced a lot of exchanges, and even entire countries, to stop dealing in such coins. Those who wish to send payments anonymously can use highly secure protocols like I2P, Tor, as well as its newest edition, the Wraith protocol.
Verge isn't even private. Wraith protocol was a disgrace. They openly leaked their users' IP addresses.
Verge was hacked twice in as many months. The devs (both times) were utterly clueless about how to fix their code. The first time the accidentally forked their coin without even realising it. The second time they stole another coins' code from Github and lied about it being their own. Even Pornhub is using a different cryptocurrency for their upcoming competition.
Verge is a scam with an incompetent team behind it. If you want an actual privacy coin to invest in I would suggest Monero.
