 I want to know if I can use the same bitcoin address in two different sites

What site? If you are talking about online wallets, don't even use them in the first place.

If you are talking about receiving coins or sending coins from and to the same address, it is absolutely safe and normal to do so. The only concern with using an address more than one is the privacy complication that it may have. Eg, if you send coins to two different sites from the same address, it would be clear that the two accounts are connected. Same goes for receiving.

I don't see it as a huge concern though.

Im talking about put the same bitcoin address in two different website to mining or make bitcoins or something like this

You can do that yes.

You can receive bitcoins from multiple places on one adress, there is absolutely no problem with that, unless you are doing alot of micro transactions, effectively creating "dust", see here for more information.

Say you use Nicehash for your CPU mining and another site for your GPU mining, ( it isn't a good idea, but possible ), then there should be no issue to use the same adress of your hardware wallet for both of these sites / programs.

And is this a safe way to accumulte my bitcoins or is it better to have different address in different wallets?

It is better to have a different address for every transaction.

A bitcoin address is NOT an account number.  It is more like an invoie number (it allows you to determine who paid you, when they paid you, and why they paid you).

You wouldn't re-use the same invoice number for multiple payments from different people (or even multiple payments from the same person), would you?

And do you know any safe wallet that will be useful to have different address for diferrent cryptocurriencies?

I personally used Jaxx.io, although some people deem this one unsafe due to vulnerabilities, however i have never had any issues. -> https://jaxx.io/support.html it supports ~12 coins,  BTC, LTC, ETH, DASH (not on iOS), ETC, REP, ZEC (not on iOS), DOGE, ICN, GNT, GNO, DGD

But i am also hearing alot of positive things about Coinomi, https://coinomi.com/ which supports over 64 coins currently.

As always use them at your own risk.

DO NOT USE JAXX

I have seen several reports on this forum from people that have lost money due to bugs in the Jaxx software!


I do not use ANY altcoins.  99% of them are scams. I ONLY use bitcoins.

If you want to know about altcoins, you'll need to ask in the altcoin sub-forum.  This is the "Technical Support" sub-forum for Bitcoin Core.

yes, you are right, but I'm asking for a site where I can accumulate Bitcoins and Ethereums, not onlu ethereums

This "Technical Support" sub-forum is for "Questions regarding issues with Bitcoin Core, nodes, the Bitcoin network, transactions, and addresses"

If you have a technical question about Bitcoin Core, about Bitcoin Nodes, about the Bitcoin Network, about Bitcoin Transactions, or about Bitcoin Addresses, please ask it.

If you want to know what wallets and services also support coins that are NOT Bitcoin, then that is neither a Technical question nor a Bitcoin question.  You'll need to ask people that know that type of thing.  They mostly read and respond to posts in the altcoin sub-forum.  I suggest asking your question there instead.
