I think if you want to Ethereum in this time, you should holding it for a long time. The market is too fluctuate and as you see, the market seem to green but I'm not sure anything might happen.
For me investing in etherum now is not connected to hodl for a really long time, first pumps will come in soon months for me and if you want to collect bigger income you will need to hodl it longer.
If it is true that later there will be a Pump, then this is the right time to buy Ethereum and hold it for long term.
I am also sure the price ETH will be high back reach up to $1000 per ETH.
I also hold a lot of ETH and I hope that it will grow again in the future. Currently ETH is declining quite a lot due to ICO projects selling tokens to ETH and exit fiat so the value of ETH is difficult to increase in this period. This is a very good time to buy ETH for a good price and keep it in the long run.
