Looking at ETH/BTC chart - https://in.investing.com/currencies/eth-btc-chart
It seems it'll be bad idea if you're planning to exchange ETH to buy BTC in coming days. Sharing review with some technical touch by observing 5 hour chart -
Pair price has been reached nearby to its max support region ~0.0675, which is lowest bet you can get on exchange ETH with BTC now a days. BTC might cost you more & you gonna definitely blaim yourself, if you exchange in coming days ~3-4 days minimum, unless its indispensable thing.
The days I' m predicting is just rough estimation, as EMA showing momentum towards establishing next support line. Hence, we should wait few days, until ETH strengthen against BTC, as MACD shown good divergence to lift up.
Hence, let this downward sentiment over & reach to its nearby resistance region ~0.078+, before we plan to go ahead spending our valuable ETH.
Hope it helps.
