<p>Yes, if you control the private key related to the address you control the funds. However, care must be taken while doing that. BCH supports legacy addresses of P2PKH starting with 1 and P2SH addresses starting with 3. However, BCH does not support segwit types. By default Bitcoin Core generates a segwit address of P2SH(P2WPKH) form. BCH supports P2SH addresses (ones that start with a 3) but it doesn’t support segwit address of P2SH(P2WPKH) form which also start with a 3. To avoid ambiguity, the ATM must have shut off sending it to addresses starting with 3</p>

I just went to a BCH ATM and it would not accept the address.  Tried the address at a BTC ATM and it worked fine.

The update to your question provided more clarity. I'm updating my answer to reflect this. By default Bitcoin Core generates a segwit address of P2SH(P2WPKH) form. BCH supports P2SH addresses (ones that start with a 3) but it doesn’t support segwit address of P2SH(P2WPKH) form which also start with a 3. To avoid ambiguity, the ATM must have shut off sending it to such addresses.

<p><strong>UPDATE ONE:</strong></p>

<p>It seems I might have answered my own question.  I took an address generated on bitcoin-core 0.17.1 to a BCH ATM and it would not get accepted as a valid address.  I then took the same address to a BTC ATM and it was accepted as a valid address.</p>

<p>Therefore, is it safe to assume that the addresses generated by bitcoin-core 0.17.1 are not compatible with BCH?</p>

<p>If it is not copatible with BCH, why does it show up as a valid address on blockchain.info for both BTC and BCH?</p>

<hr>

<p><strong>ORIGINAL QUESTION:</strong></p>

<p>I've just created a new receiving address in bitcoin core 0.17.1 and noticed that it starts with a 3.  I then posted this address into blockchain.info to make sure no one else has miraculously generated the same address.  It was a new address.</p>

<p>But I noticed, that the address were appearing as both a BTC and BCH address.</p>

<p>Does this mean I can send BTC and BCH to this address?</p>

**UPDATE ONE:**

It seems I might have answered my own question. I took an address generated on bitcoin-core 0.17.1 to a BCH ATM and it would not get accepted as a valid address. I then took the same address to a BTC ATM and it was accepted as a valid address.

Therefore, is it safe to assume that the addresses generated by bitcoin-core 0.17.1 are not compatible with BCH?

If it is not copatible with BCH, why does it show up as a valid address on blockchain.info for both BTC and BCH?

But I noticed, that the address were appearing as both a BTC and BCH address.

Does this mean I can send BTC and BCH to this address?
