I prefer litecoin to ripple because of the following advantages that Litecoin has over ripple;
1. Scrypt Algorithm: GPU’s are used to mine Litecoin efficiently and, as a result, ASIC miners are kept at bay to ensure there is sufficient Hash power to be distributed equitably among all the users.
2. SegWit and the Anti-Spam filter: Litecoin pioneered the component of using spam filters to maintain a blockchain size that can be kept limited, thanks to SegWit and ant-spam filters.
3. Fast transaction times: We already mentioned here that Litecoin has perhaps the quickest block timing, therefore, making it a preferred cryptocurrency among users.
4. Buzzing community: Litecoin has got one of the most progressive communities and core #DevelopmentTeam  that provides ready answers for any burning questions. The high quality of interaction has made it a popular cryptocurrency among users.

I prefer Zcash because  being a privacy-focused blockchain and cryptocurrency  was developed in response to bitcoin’s flaws. It uses the same algorithm as bitcoin but improves upon it by enabling semi-transparent processing. In simple words, this means that it eschews the radical transparency of bitcoin’s blockchain for a more nuanced implementation. However, it has several drawbacks but yet still its worth to invest in it.

Though its possible for bitcoin to hit 20k by close of year as many crypto analyst are hopeful of that, its however quite unlikely to occur considering the instabilities in the market.

I invest in Dash because Dash has become one of the strongest cryptocurrencies worldwide. It continues to prove its spot in the industry as it becomes more and more relevant to the masses. It has become one of the fastest-rising cryptocurrencies worldwide. It has never-broken privacy and It’s much more decentralized than most coins.

Ripple coin, which trades as XRP, is the cryptocurrency described as 1,000 times faster and 1,000 times cheaper than a Bitcoin transaction. Notably, XRP transactions are also much less expensive than traditional methods of transferring money and allow transfers to be completed in seconds as opposed to hours or even days for traditional bank transactions.

Even though BTG is a cryptocurrency with Bitcoin fundamentals, mined on common GPUs instead of specialty ASICs.
ASICs tend to monopolize mining to a few big players, but GPU mining means anyone can mine again - restoring decentralization and independence. GPU mining rewards go to individuals worldwide, instead of mostly to ASIC warehouse owners, recreating network effects that Bitcoin used to have. Yet still bitcoin has the largest community based and is the most trusted and accepted coin. I therefore prefer bitcoin to BTG.

As long as Bitcoin exists, there can only ever be 21 million — no more. So, if the popularity of Bitcoin increases, so will the Bitcoin price predictions. The price for now is not stable but has the potential to rise higher by close of year.
