I think that the year 2019, on the contrary, will be very successful for ethereum and he will be able to show an excellent result
I totally agree with you that 2019 is probably an extremely good year to invest Ethereum at a good price this year. This is necessary to go one step further in the crypto market, because the previous upheaval I lost was almost complete and I need this time to recover

Yes, ethereum has a lot of potentials, yet that does not mean you should not be careful when investing in it.
Imagine how some people were cajoled into buying eth at the announcement of the of the hardfork, yet it dump.
The point at which one comes in is very essential, because it will determine how much profit you will get.
If I buy low, I can be very patient to hold, perhaps it will experience a high growth rate.
