My top 4 Cryptocurrencies for 2018 are Bitcoin, Etherum, Ripple, and Tron.
Bitcoin is first on my list because it is the market dominator. All altcoins descended from Bitcoin, and are mainly bought via Bitcoin transactions. For example if i wanted to trade in my PotCoins for USD i would first exchange it to Bitcoin and then to USD. As long as Bitcoin remains the medium of transactions for cryptocurrencies, its price will rise as the total crypto market cap rises.
As for Etherum, i put it on my list of top 5 cryptos, because “Ethereum is an open software platform based on blockchain technology that enables developers to build and deploy decentralized applications”. That is, as long as new cryptos are being created, which in my opinion will go on for a while, Etherum will remain.
Ripple is also one of my favourite because of its outstanding performance this past year. I personally invested in Ripple at 0.03$, so to see it at 3$ and growing is awesome. Although, i do see a limit to how much a Ripple can be worth. Ripple is second largest market cap, so with ripple at 3$ for it to get to for example 15$, its market cap whould have to increase by a factor of 5. For this, ripple would be sitting at a market cap of over 600$ billion or almost the whole market cap for cryptocurrencies. This is also due to ripple having such a large supply. With a large supply, for 1 ripple to be worth alot, the market cap must be huge.
As for Tron, it is a fairly new Cryptocurrency and so i havent seen yet how it would react to a slow market. Ive only been watching Tron recently and it has grown tremendously but the crypto market cap too has been growing. Tron has done so great this past week, reaching 6th largest market cap, that i do believe it is here to stay in the top market caps. Although there are rumours of Tron partnering with Alibaba. If that were to happen, I see Tron taking 2nd position in largest market cap, right before Bitcoin.
