I bought and received profit. It really has high risky but it also give me a higher profit. I usually trade it for short-term, so I buy only altcoins those which has high liquidity.
Don't advice financial, but for me, I will buy Bitcoin only in bear market now (let's do your own search to find the good point to buy). Let's see the market, almost altcoins dump or pump following bitcoin, so it is my choosing.
I have seen Ethereum Classic Vision - a hard fork of ETH, any one holds ETH in personal wallet they will get 3 ETCV for each ETH. Hard fork will happen on Jan 11, 2019. I don't advice financial so let's do your own search to decide. For me now, the ETH's price isn't too high to buy.
In 2019, I hope that bear market will end soon and market will move to bullish the the price will reach an other top. And best wishes to us including holders, traders and newbies those who begin to join crypto market.
No one can predict exactly the future and crypto market too. I saw a lot of investors have lost their money in 2018 because they have seen many bright prediction for crypto market in 2017. Today is end of 2018, I hope that we will have the bright future for crypto in 2019.
Many investors lost their money, I also hope that it can reach $300 in end of this year. But I think it's so hard to hit. We have only 8 days left for 2018 and I see only the price can reach $140 - $150.
I don't advice financial, but in your list, Pundix has a strong community and hype potential. For BAT, it listed on Coinbase, it's also a good coin to invest.
Nothing is sure in this market, no one can know exactly what will happen. We can only predict and pray for a bright future. Let's look back 2017, We have seen many amazing prediction for the price of bitcoin/ altcoins. And now, almost investors have lost their fund. LOL
