https://fundgoat.com/wp-content/uploads/2017/05/cryptocurrency-war.png Firstly, I invested a bit with bitcoin and it gave me surprises, and now I'm more interested in cryptocurrencies, ofcourse Steem is one of my choice now, I think there is far more potential of Steem in the future. I do have interest and research about other cryptocurrencies than just bitcoin, and hence this is just an opinion I would like to share.

Strongest Coin to Hold

SiaCoin -

Could storage decentralized is a very huge market and I think they beat out their competition of Storj. The dev team and community is very active as well. I see this as a long term coin but it needs to start pushing out the market share of Amazon, Google, and others in the could space.

Monero -

Anonymous currency that is fast and fixes some of the main problems bitcoin has.

Ethereum -

Pretty straight forward here as it is a highly valuable coin in the smart contract landscape. Seems slightly overvalued right now but I see it as a contender with bitcoin in 2+ years in terms of market cap.

BitShares -

Similar to waves but has a longer track history and is completely decentralized. I like the idea for both and agree that the UI for waves is better overall. I think Waves is very overpriced atm and this fills the same niche with the same quality. It will all come down to adoption and I can see both succeeding but am placing value here because of price and road map.

Coins that have potential

BitBay/Lykke: Both very similar but for different markets right now. I see BitBay as getting more value right now but both seem good to me.

Steem -

Social currency with one of the best communities I have seen. It has been here for a long time and I see it growing. I like Steem.it but it could use some changes overall. If they can gather enough people understand it I feel like the growth will be great.

ReddCoin -

Similar to Steem but also for micro tipping across various platforms. This community is one of the best I have seen and the focus is good. The new ReddID is coming out later this month and could change things for the better. The POS is also interesting and good for me with my amount of coins.

NEM -

A marketplace of itself that is very active in Asia and growing fast. I do not see this reaching over a $1 in the next year but I still see long term growth for the coin.

GridCoin -

Golem but with a working and stable application. Has been around for much longer but has stayed somewhat under the radar. I would either go this or Golem but Golem seems to be very hyped and overvalued at the moment.

GameCoin -

This one I am the most iffy but see the long term potential. If this can be implimented into any gaming platform (App store, steam, etc.) the profits could be huge. Besides that it also has a gambling aspect that is interesting.

Others that are interesting/potential/not fully researched -

PIVX: Interesting form of currency and growth. SysCoin & Lisk

Coins I would PREFER to Avoid

Ripple -Banks, government, the opposite of crypo, and pumped a lot
Dash - Monero is just better so bye
Stratis - Pumped and all speculation
Ethereum Classic - I just don't see how it succeeds in the shadow of Ethereum
ByteCoin - Lots of sketchy stuff going on here

Conclusions:

It would be better if you can do some researches on the coins before invest, don't just follow without knowledge as it is very dangerous. Any comments or ideas of new coins would be welcomed and appreciated.
