Today ETH has reached 138 $, this is the worst price this year. Vitalik itself is announcing laounching Etherium 2.0, but it has no effect until now. Will it reach under 100 $ for tonight? 
There is no cause for alarm. Even if it dumps below, i will buy more. If you are unable to take some reasonable risks, i do not knowhow successful one can be. Where i am today and what i have been able to achieve, are by virtue of the risks I have been able to take. There is no need to panic, whatever would happen, in the long run, I believe and envisage it will be profitable.
