If I had 1BTC I would definitely sell when the market rises and buy bitcoins again when the market falls. I will invest in coins like Ethereum with the profit I get during this period but after Bitcoin I will not prepare myself to invest in any currency other than Ethereum. I will always force myself to go with low risk coins I will never force myself to invest in high risk coins. Because I don't like to take too much risk I always prefer to proceed with less risk.
