FOUR FACTS no one here will give you (Since they don't want to help you, just for you to invest and hold for more value and better for them).
1º) by the end of 2017 more than 95.000.000.000 € were invested in ETH. nowadays market capitalization is arround 67.000.000.000 €. Do you still think this is going well for ETH??
2º) By the end of 2017, the total network hashrate of ETH was about 130.000GH/s. Nowadays its 235.000 GH/s, so the number of people mining ETH has almost doubled in just 3 months, which has terrible consecuences.
3º) Linked to the 2º fact, The more people enter ETH, the more difficult it's to get more profit. This is A FACT : When in October 2017 the difficulty reached 3.0, Vitalik applied Byzantium, which implied that block length was reduced from 24s to 15s and from 5 ETH per block to 3.
Today, we are a max hashrate and the difficulty is more than 3,2. So, EVERYBODY IS GETTING LESS ETH by mining. and due to the fact that the miners are in only for direct profit (cause monthly you´ll have to pay the bill), THIS IMPLIES THAT THE MORE MINERS ENTER THIS, THE MORE VOLATILITY OF THE PRICE, so the worst for all.
4º) Vitalik has said that he will not allow ETH to continue generating coins (the more coins the less value at the end) and he will apply Casper with a difficulty Bomb by switching to PoS, which will destroy mining since it will be IMPOSIBLE TO MINE, and on the other hand, probably only people with at least 10 coins will be able to enter. The others (those with very little to no complete coin) will be offered and unknown solution.
Continue recomending ETH, continue., OMFG
